La comparaison entre les terpènes d'origine végétale et ceux issus du cannabis est l'une des plus importantes à prendre en compte lors du choix d'un profil terpénique. Les deux peuvent contenir exactement les mêmes molécules de terpènes, mais la manière dont ces composés sont obtenus, combinés et présentés peut donner lieu à des profils aromatiques très différents.
Les terpènes d'origine végétale, souvent désignés par l'abréviation « BDT », sont extraits de plantes autres que le cannabis, telles que les agrumes, les conifères, les herbes aromatiques, les fleurs et les épices. Les différents terpènes naturels peuvent ensuite être mélangés selon des proportions contrôlées afin de créer un arôme original ou de reproduire les principales caractéristiques d'une variété de cannabis.
Les terpènes dérivés du cannabis, généralement désignés par l'abréviation « CDT », proviennent directement de la plante de cannabis. Plutôt que de reconstituer un profil à partir d'ingrédients provenant de sources distinctes, l'objectif est généralement de restituer une partie de l'empreinte volatile naturelle produite par la plante d'origine.
Aucune de ces deux catégories n'est automatiquement supérieure. Les terpènes d'origine végétale peuvent offrir une cohérence, une évolutivité et un contrôle de la formulation exceptionnels. Les terpènes issus du cannabis permettent quant à eux de préserver un arôme de cannabis plus authentique, contenant les principaux terpènes ainsi que des composés volatils mineurs naturellement associés.
Ce guide compare en détail les terpènes d'origine végétale et les terpènes dérivés du cannabis, notamment en ce qui concerne leur composition chimique, leur arôme, leur extraction, leur consistance, leurs composés mineurs, leur coût, les analyses, la présence résiduelle de cannabinoïdes, la réglementation britannique et le lien entre les CDT et les terpènes issus de la résine fraîche.
La principale différence entre les terpènes botaniques et les terpènes dérivés du cannabis réside dans leur origine et la composition de leur profil. Les terpènes botaniques sont obtenus à partir de plantes autres que le cannabis et peuvent être mélangés pour reproduire un arôme défini avec une grande homogénéité d'un lot à l'autre. Les terpènes dérivés du cannabis sont extraits directement de la matière première et permettent de conserver une empreinte volatile plus large, propre au cultivar d'origine. Des molécules individuelles telles que le limonène, le myrcène ou le bêta-caryophyllène peuvent être chimiquement identiques, quelle que soit leur source botanique. La différence réside principalement dans le mélange complet qui les entoure.
Les principales différences entre les terpènes d'origine végétale et ceux issus du cannabis.
| Fonctionnalité | Terpènes botaniques | Terpènes dérivés du cannabis |
|---|---|---|
| Source | Plantes autres que le cannabis, telles que les agrumes, les conifères, les herbes aromatiques, les fleurs et les épices | Matériel végétal de cannabis |
| Abréviation courante | BDT ou terpène d'origine végétale | CDT ou terpène dérivé du cannabis |
| Création d'un profil | Généralement élaborées à partir d'ingrédients végétaux bien définis | Extrait du profil de la plante d'origine à l'état naturel |
| Identité d'une molécule donnée | Peut être identique à la molécule correspondante présente dans le cannabis | Produit naturellement par le cannabis |
| Cohérence des lots | Peut être contrôlé de manière très rigoureuse | Des variations naturelles liées à l'agriculture et au lot peuvent survenir |
| Composés volatils mineurs | Cela dépend de la complexité de la formulation | Permet de conserver les composés volatils mineurs du cannabis présents naturellement |
| Conception olfactive | Très modulable | Cela dépend principalement de la variété d'origine et du procédé d'extraction |
| Résidus de cannabinoïdes | Absence de source de cannabinoïdes issus du cannabis lorsque seuls des ingrédients non issus du cannabis sont utilisés | Possible en fonction de l'extraction et du raffinage |
| Évolutivité | Dans l'ensemble, excellent | Cela dépend davantage de la biomasse de cannabis et du rendement d'extraction |
| Coût | Généralement plus économique | Souvent plus coûteux en raison de la nature spécialisée des sources et de la récupération |
| Attraction principale | Cohérence, flexibilité et maîtrise de la formulation | Fidélité à la composition chimique aromatique naturelle du cannabis |
Les terpènes botaniques sont des composés terpéniques issus de sources végétales autres que le cannabis.
Le choix de la plante comme source commerciale dépend généralement de la molécule qu'elle produit naturellement de manière efficace.
En voici quelques exemples :
L'huile végétale peut être extrait puis raffiné ou fractionné jusqu’à l’obtention de composants terpéniques individuels ou de fractions riches en terpènes.
Ces ingrédients peuvent ensuite être mélangés selon des proportions bien définies.
L'abréviation « BDT » désigne généralement un terpène d'origine végétale.
Ce terme est couramment utilisé pour distinguer les profils terpéniques issus d'ingrédients botaniques autres que le cannabis de ceux extraits directement du cannabis.
Le BDT ne désigne pas une formulation chimique spécifique.
Le profil terpénique d'une plante peut ne comporter que quelques composants principaux ou bien des dizaines de composés, principaux et secondaires, soigneusement sélectionnés.
La qualité d'un profil BDT ne se résume donc pas à son acronyme.
Les terpènes issus du cannabis sont des composés aromatiques extraits directement de la plante de cannabis.
On les appelle communément des CDT.
En fonction de la matière première et du procédé d'extraction, une fraction de terpènes issue du cannabis peut contenir un large éventail de composés volatils associés à un cultivar ou à une récolte en particulier.
Parmi ceux-ci, on peut citer des terpènes bien connus tels que :
Des terpénoïdes oxygénés tels que le linalol, le nérolidol et le bisabolol peuvent également faire partie du profil volatil.
Certaines fractions aromatiques issues du cannabis peuvent en outre contenir de faibles concentrations de composés n'appartenant pas à la famille des terpènes, qui contribuent de manière significative à l'arôme final.
CDT signifie « terpène dérivé du cannabis ».
Ce terme indique l'origine de la matière aromatique.
Elle ne précise pas exactement comment la matière a été extraite, si du cannabis frais ou séché a été utilisé, si des cannabinoïdes sont encore présents dans la fraction finale, ni quel pourcentage de la matière est constitué de terpènes identifiés.
Deux produits portant tous deux la mention « CDT » peuvent donc présenter des différences significatives en termes de composition et de qualité.
Pas nécessairement.
Une molécule de limonène présentant la même structure moléculaire et la même stéréochimie reste cette même molécule, que la plante d'origine soit un zeste d'orange ou du cannabis.
Le même principe s'applique à :
La source végétale ne crée pas une nouvelle version de la molécule simplement parce que l'espèce botanique a changé.
La différence essentielle réside généralement dans la composition du mélange final.
En effet, l'arôme résulte d'un mélange et non d'une seule molécule.
Une variété de cannabis et une orange peuvent toutes deux contenir du limonène tout en ayant des odeurs complètement différentes.
L'arôme perçu dépend :
Des concentrations très faibles de composés aromatiques puissants peuvent parfois influencer l'ensemble de la odeur plus fortement qu'une quantité bien plus importante d'un composé à l'odeur relativement peu prononcée.
La recherche sur les arômes du cannabis a dépassé l'idée selon laquelle les pourcentages des principaux terpènes expliqueraient à eux seuls l'arôme de chaque variété.
Le cannabis produit également de nombreux composés volatils qui n'appartiennent pas à la famille des terpènes.
Il peut s'agir notamment :
Certaines de ces substances peuvent dégager des odeurs extrêmement fortes, même à de très faibles concentrations.
Cela permet d'expliquer pourquoi deux échantillons de cannabis présentant des profils de terpènes principaux globalement similaires peuvent néanmoins avoir des odeurs radicalement différentes.
Pas au sens où on utilise habituellement le terme « CDT ».
Les flavonoïdes constituent une famille distincte de composés végétaux.
Elles sont généralement bien moins volatiles que les molécules présentes dans une fraction aromatique classique riche en terpènes.
Le cannabis contient indéniablement des flavonoïdes, notamment des composés tels que les cannflavines.
Cela ne signifie pas pour autant qu'une fraction de terpènes issue du cannabis contienne automatiquement une concentration significative en flavonoïdes.
Il s'agit là d'une distinction importante entre une fraction aromatique volatile et un extrait de cannabis plus large.
Cannabis aroma can contain several different chemical families.
| Compound Type | Exemples | Potential Contribution |
|---|---|---|
| Monoterpènes | Myrcene, limonene, pinene, terpinolene | Citrus, pine, herbal, fresh and earthy characteristics |
| Sesquiterpènes | Bêta-caryophyllène, humulène | Woody, peppery, spicy and herbal notes |
| Terpenoids | Linalool, nerolidol, bisabolol | Floral, woody and softer aromatic characteristics |
| Esters | Various low-level aroma compounds | Fruit-like and sweet aromatic notes |
| Volatile sulphur compounds | Several highly potent cannabis aroma molecules | Skunky, gas-like, tropical or pungent characteristics |
| Other volatiles | Alcohols, aldehydes, ketones and heterocyclic compounds | Can strongly alter cultivar-specific aroma |
A carefully recovered CDT can preserve compounds in the ratios naturally produced by the source plant.
It can also retain minor volatiles that may not appear in a simpler reconstructed botanical profile.
This can create greater aromatic depth and a more immediately recognisable cannabis character.
That does not mean every CDT will smell better than every botanical profile.
Extraction technique, storage conditions and starting plant quality can all make a major difference.
A poorly stored CDT can lose important volatile compounds, while a sophisticated botanical reconstruction can reproduce a highly convincing strain-inspired aroma.
They can reproduce many of the major aromatic characteristics.
A formulator can analyse the major compounds within a target cannabis profile and create a blend containing comparable proportions of:
The more compounds included and the more accurately their ratios are controlled, the closer the reconstructed profile can become.
However, reproducing every trace volatile found in a particular cannabis harvest can be much more difficult.
A useful way to think about the comparison is reconstruction versus recovery.
A botanical profile is usually reconstructed.
The formulator chooses ingredients and combines them to produce a target aroma.
A cannabis-derived profile is recovered.
The starting plant has already produced the mixture biologically, and the extraction process attempts to capture part of that existing chemical fingerprint.
Both approaches have advantages.
Botanical terpene profiles offer several practical benefits.
These characteristics make botanical terpenes especially useful where consistency is the primary objective.
CDTs offer a different set of advantages.
For consumers and formulators prioritising source authenticity, these features can be particularly attractive.
The main limitation is that a reconstruction is only as detailed as the formulation used to create it.
A simple blend based on three or four dominant terpenes may reproduce the general direction of a cannabis cultivar while missing the subtler aromatic compounds responsible for depth and recognisable strain character.
This is why two products both marketed as the same strain-inspired botanical profile can smell very different.
The formulation quality matters.
Natural cannabis-derived profiles can be less straightforward to standardise.
Differences can arise from:
Cannabis-derived production can also involve more complex regulatory considerations because the raw material is cannabis and cannabinoid carryover may need to be assessed.
Botanical profiles generally offer greater formulation control.
If a formula specifies an exact mass of limonene, pinene, myrcene and beta-caryophyllene, the same ratios can be recreated repeatedly using characterised ingredients.
A natural cannabis crop cannot be expected to reproduce its volatile profile with exactly the same percentages across every harvest.
This does not make CDTs inconsistent in a quality-control sense.
Manufacturers can standardise batches, blend production lots and work within defined specifications.
It simply means the raw agricultural material contains inherent natural variation.
A native cannabis-derived fraction can contain a highly complex volatile fingerprint.
However, the word cannabis-derived does not automatically guarantee greater complexity.
An extraction method can selectively recover only part of the plant’s aromatic chemistry.
A carefully formulated botanical profile can also contain a substantial number of ingredients.
The most meaningful comparison is therefore the actual analytical profile rather than the source name alone.
Both can be naturally plant-derived.
A botanical terpene extracted from orange, pine, lavender or another plant is still a naturally occurring plant molecule.
A cannabis-derived terpene is also naturally plant-derived.
The distinction is the species from which the ingredient originated.
Natural should therefore not be used as shorthand for cannabis-derived.
Pas nécessairement.
Botanical terpenes can be isolated directly from naturally occurring plant oils.
For example, limonene can be recovered from citrus-derived material.
That is different from chemically synthesising limonene through an industrial chemical process.
Both routes can theoretically produce the same molecular structure, but they are different manufacturing origins.
The term nature-identical is sometimes used loosely when discussing terpene ingredients.
It should not be confused automatically with botanical-derived.
A compound produced through chemical synthesis can be molecularly identical to a compound that occurs in nature.
A botanical terpene physically extracted from a plant is instead naturally derived.
When sourcing ingredients, the supplier documentation should state the actual origin rather than relying solely on marketing terminology.
These are separate categories.
Botanical terpenes are obtained from plant material.
Synthetic terpenes are produced through chemical synthesis.
If the final molecular structure and stereochemistry are identical, the individual molecules can be chemically equivalent.
Differences may still exist in:
Modern biotechnology provides another production route.
Engineered microorganisms can be used to produce specific terpene molecules through fermentation.
The target compound is then recovered and purified.
This can provide highly consistent supply without relying entirely on conventional agricultural extraction.
Our full guide to Comment les terpènes sont-ils produits et extraits ? explains botanical extraction, distillation and biological manufacturing in greater detail.
There is no single botanical terpene extraction method.
The process depends on the plant material and target molecule.
Common techniques include:
Citrus is a particularly useful example because the peel contains abundant oil glands and can provide large quantities of limonene-rich essential oil.
CDTs can also be produced using several different recovery technologies.
Depending on the manufacturer and intended specification, these can include controlled distillation, volatile recovery and specialised extraction systems.
The important point is that the phrase cannabis-derived terpenes does not define one universal extraction process.
Two CDT products produced using different methods can therefore contain noticeably different aromatic fractions even when the cannabis genetics are similar.
Oui.
Extraction is selective.
Different processes expose the material to different combinations of:
These factors affect which volatile compounds are recovered and how well they survive processing.
For this reason, extraction method can be just as important as botanical source when evaluating a terpene profile.
Live resin terpenes are a more specific form of cannabis-derived aromatic material.
Live resin processing begins with freshly harvested cannabis that is rapidly frozen rather than being dried and cured before extraction.
The objective is to preserve more of the fresh plant’s volatile chemistry.
A botanical profile is different because it is created using terpene ingredients sourced from non-cannabis plants.
Botanical terpenes and live resin terpenes compared.
| Fonctionnalité | Terpènes botaniques | Terpènes de résine fraîche |
|---|---|---|
| Source | Non-cannabis plants | Cannabis frais congelé |
| Création d'un profil | Formulated from selected ingredients | Recovered from the native source plant |
| Exigences relatives aux produits frais surgelés | Non | Élément central de la désignation « en direct » |
| Cohérence | Can be extremely consistent | Natural batch variation possible |
| Native cannabis volatiles | Only where deliberately included using suitable ingredients | Can retain a broader native fresh-cannabis fingerprint |
| Résidus de cannabinoïdes | No inherent cannabis cannabinoid source | Possible and should be tested where relevant |
For the full comparison, read what are live resin terpenes?
Non.
All genuine live resin terpenes are cannabis-derived, but CDTs can also be recovered from cannabis that has been dried, cured or processed using other methods.
CDT describes botanical source.
Live resin describes a more specific fresh-frozen starting material and extraction concept.
Drying and curing can alter cannabis volatile chemistry.
Highly volatile compounds can be lost from the plant over time, and the relative ratio between lighter monoterpenes and heavier sesquiterpenes can shift.
Oxidation and other chemical reactions can also occur.
This means a CDT derived from dried cannabis may represent a different stage of the plant’s aroma chemistry from a live resin terpene profile made from fresh-frozen material.
Pas automatiquement.
Full spectrum and cannabis-derived terpenes describe different things.
A highly refined CDT may contain a broad range of volatile compounds while containing very few cannabinoids.
A broad cannabis extract can contain cannabinoids, terpenes and many other constituents.
The words CDT do not tell you whether the material is a full-spectrum cannabinoid extract.
They can, but they do not have to.
THC and terpenes are chemically different compounds.
However, both can originate from the same cannabis resinous material.
An extraction process may therefore recover trace or measurable cannabinoids alongside the volatile fraction unless they are effectively separated.
A product described as cannabis-derived terpenes should not automatically be assumed to contain THC, and it should not automatically be assumed to contain none.
The correct answer comes from analytical testing.
A genuine botanical profile made exclusively from non-cannabis terpene ingredients has no inherent reason to contain cannabis cannabinoids such as THC.
This is one practical advantage where controlled-cannabinoid avoidance is important.
Normal manufacturing quality controls still matter because cross-contamination, mislabelling or unsuitable supply chains can occur with any ingredient.
The product specification should remain the basis for assessment.
Botanical terpenes provide the simpler starting point because their source plants do not naturally manufacture cannabis cannabinoids such as THC.
CDTs require a different quality-control question.
The terpene molecules themselves are not THC, but the extraction began with cannabis material.
Cannabinoid screening can therefore be particularly important.
Common terpene molecules such as limonene, myrcene, pinene and beta-caryophyllene are not controlled drugs merely because those molecules also occur in cannabis. Cannabis itself and a number of cannabinoids are controlled under UK drugs legislation. The regulatory position of a cannabis-derived terpene material therefore depends on its actual composition and the activities involved in producing, importing, possessing and supplying it.
Botanical terpene ingredients made exclusively from non-cannabis plant sources avoid the specific issue of controlled cannabinoid carryover from cannabis biomass.
They still need to meet any safety, labelling, chemical and product-specific requirements relevant to their intended application.
CDTs require closer attention to the cannabis supply chain.
Home Office guidance makes an important distinction between a finished material and the controlled cannabis material used earlier in production.
Handling controlled cannabis plant parts or non-exempt bulk cannabinoid-containing material can require the appropriate licence even where a later finished product may qualify for an exemption.
The widely quoted 0.2% figure is not a general finished-product THC limit.
It relates to the UK’s low-THC industrial chanvre cultivation framework and approved varieties.
It should therefore not be used as a blanket rule for cannabis flower, resin, extracts or cannabis-derived terpene ingredients.
Les juridique status of a finished material depends on the relevant legislation, its composition and the activity being undertaken.
The one milligram figure forms part of the exempt-product definition under the Misuse of Drugs Regulations.
It is not a general statement that every cannabinoid product is lawful whenever it contains less than one milligram of a controlled substance.
The exempt-product definition contains multiple requirements that must all be satisfied.
Home Office guidance also emphasises appropriate analytical testing where reliance is placed on that definition.
This matters for cannabis-derived aromatic ingredients because a seemingly small cannabinoid concentration can translate into a different total quantity depending on container size.
Terpene molecules are not the THC metabolites targeted by standard cannabis drug tests.
The relevant question is whether the complete CDT material contains a controlled cannabinoid.
A properly characterised cannabis-derived terpene fraction with no relevant cannabinoid contamination presents a different scenario from a broad cannabis extract containing THC.
Lire Les terpènes sont-ils détectables lors d'un test de dépistage de drogues ? pour obtenir des explications détaillées.
A non-cannabis botanical source removes the inherent cannabis cannabinoid carryover question.
That makes botanical ingredients easier to assess from this particular perspective.
It is still better to rely on traceable ingredient documentation rather than assuming that every product sold as botanical has been manufactured correctly.
Neither source category guarantees purity.
A botanical terpene isoler can be produced to extremely high purity.
A cannabis-derived terpene fraction can also be highly refined.
Likewise, either category can be poorly processed or inadequately documented.
Purity should be determined from analytical specification, not from whether the label says botanical or cannabis-derived.
A useful terpene Certificate of Analysis or specification may include:
The presence of the letters COA does not mean every relevant test has necessarily been performed.
Gas chromatography is particularly useful for terpene analysis because many aromatic compounds are volatile enough to be separated effectively in the gas phase.
GC-MS combines chromatography with mass spectrometry and can help identify individual compounds.
GC-FID is also widely used for quantitative terpene analysis.
More advanced methods may be required when very low-concentration aroma compounds need to be identified.
Many routine terpene panels se focaliser on a defined list of common compounds.
This is useful for measuring major terpenes but does not necessarily characterise every volatile molecule responsible for aroma.
Some compounds that strongly influence cannabis smell occur at very low concentrations and can require more specialised analytical methods.
This is one reason a terpene COA and the sensory character of a CDT do not always appear to tell exactly the same story.
Non.
Starting cannabis quality is critical.
If the plant material has been poorly stored, overheated or allowed to oxidise, an authentic cannabis source cannot restore compounds that have already been lost.
A CDT can also be damaged after extraction through:
Source matters, but handling matters too.
Pas nécessairement.
A simple botanical blend containing four dominant terpenes may smell relatively generic.
A highly detailed formulation using a wider range of major and minor ingredients can reproduce much more of a target aroma.
Botanical reconstruction exists on a spectrum.
The relevant question is how sophisticated the profile is, not merely whether it is botanical.
A well-produced CDT generally has an advantage when the objective is to preserve the naturally occurring volatile fingerprint of a particular cannabis source.
That is because the plant itself determined the original ratios.
Modern botanical formulation can nevertheless produce extremely convincing cannabis-inspired profiles, particularly where the objective is a recognisable strain family rather than a forensic copy of one specific harvest.
There are two different interpretations of strain specific.
A botanical strain profile can be formulated to recreate the recognised aroma associated with a cultivar name.
A cannabis-derived strain profile can be physically recovered from plant material identified as that cultivar.
The first is a reconstruction.
The second is a source-derived profile.
Both can legitimately be strain-related products, but they mean different things.
Oui.
Plant chemistry is influenced by genetics and environment.
Two batches associated with the same cultivar name can differ because of:
This natural variation is part of the difference between agricultural extraction and a fixed laboratory reconstruction.
Oui.
A defined formula can be reproduced repeatedly using measured ingredients.
If each ingredient meets specification, the resulting profile can remain extremely consistent between manufacturing batches.
This level of reproducibility is one of the le plus fort advantages of botanical terpene formulation.
Botanical terpene profiles are generally less expensive to manufacture at scale.
Many target molecules can be sourced from plants that produce them abundantly or from established essential-oil supply chains.
Cannabis-derived terpene production can require more expensive biomass, specialist handling, lower aromatic yield, cannabis-specific processing and additional analytical control.
The exact price difference varies widely, so there is no meaningful universal rule such as CDT always costing a particular multiple of BDT.
Several factors can contribute:
The final aromatic fraction can represent only a relatively small proportion of the original plant material.
Non.
Price can reflect a more expensive production route without guaranteeing a better ingredient.
Quality should be assessed using:
A high-quality botanical profile can outperform a poorly produced CDT for many purposes.
If the individual molecule is chemically identical and presented at the same concentration, its source plant does not create an entirely different molecule.
What can differ is the complete profile.
A CDT may contain additional native volatile compounds that are absent from a simpler botanical reconstruction.
Whether those differences produce meaningful physiological effects is a separate scientific question from whether they change aroma.
Evidence around terpene pharmacology varies significantly between compounds.
Lire Comment les terpènes agissent sur l'organisme et influencent votre expérience for a more detailed review.
There is not enough evidence to declare one terpene source universally superior for an entourage effect.
The entourage-effect hypothesis proposes that combinations of plant constituents may interact to produce outcomes different from isolated compounds.
Some specific molecular interactions are supported by experimental research.
However, that does not establish that every CDT automatically produces stronger cannabinoid synergy than every botanical profile.
Likewise, adding a botanical terpene blend to cannabinoids does not automatically prove enhanced efficacy or improved bioavailability.
The actual compounds, concentrations and route of exposure matter.
Beta-caryophyllene helps explain why source and molecule should be separated conceptually.
It is found in cannabis, black pepper, cloves and many other plants.
Research has demonstrated activity at the CB2 cannabinoid receptor.
A beta-caryophyllene molecule does not acquire that property only when extracted from cannabis.
The molecular structure is what matters.
This does not mean every terpene acts through cannabinoid receptors.
This claim is often stated much more confidently than the evidence allows.
Some terpene compounds have been investigated as penetration enhancers or drug-delivery ingredients under particular experimental conditions.
That does not prove that every terpene profile automatically increases CBD, CBG or other cannabinoid bioavailability.
Any bioavailability claim should be demonstrated for the specific formulation and route of administration.
Sometimes, but not reliably.
A conventional simple botanical reconstruction may smell cleaner, brighter or more obviously built around major terpene notes.
A complex CDT may smell more layered, pungent or distinctly cannabis-like.
However, modern botanical formulations can be extremely sophisticated.
Aroma alone cannot prove ingredient origin.
Non.
Colour depends on composition, refinement, oxidation and storage.
Both botanical and cannabis-derived materials can range from nearly colourless to pale yellow or deeper shades depending on the product.
Source documentation is more useful than appearance.
Storage stability depends primarily on composition and packaging rather than whether the source was cannabis or another plant.
Common terpene compounds are volatile and can oxidise.
Both BDT and CDT profiles therefore benefit from:
For the complete storage guide, read Comment conserver et préserver les terpènes.
The source label itself does not control volatility.
Volatility is determined by the molecules present and their concentrations.
A limonene molecule does not gain a different boiling point because it came from cannabis instead of citrus.
However, two complete profiles can evaporate differently if their chemical compositions differ.
A monoterpene-rich profile may lose volatile components more rapidly than one containing a larger proportion of heavier sesquiterpenes.
Voir températures d'évaporation, de combustion et de dégradation des terpènes for the detailed chemistry.
Botanical profiles provide exceptional control where a formulator needs to reproduce the same aroma repeatedly.
Individual ingredients can be weighed accurately and adjusted independently.
CDTs instead provide a naturally assembled cannabis profile.
The formulator works with the chemistry supplied by the source plant rather than building that chemistry molecule by molecule.
The correct choice depends on the product objective.
From a formulation perspective, compatible terpene ingredients can potentially be combined where their documentation supports the intended application.
This can allow a formulator to use a native cannabis aromatic fraction as a foundation and adjust selected characteristics using additional botanical ingredients.
Whether that approach is appropriate depends on the target specification, labelling, regulatory context and intended application.
Both botanical and cannabis-derived terpene profiles can alter the aroma and physical properties of a compatible cannabinoid-rich formulation.
The exact behaviour depends on:
There is no universal terpene percentage that applies simply because a profile is BDT or CDT.
Lire Comment mélanger des terpènes avec du distillat for the complete formulation guide.
Both types can also be discussed in relation to botanical aroma infusion, although introducing volatile ingredients to dried flower involves different physical chemistry from mixing them into a liquid oil phase.
The porous structure of dried botanical material, moisture, headspace and volatility all influence distribution.
For the detailed guide and UK context, see Comment ajouter des terpènes aux fleurs.
The same major molecules associated with cannabis occur throughout nature.

Many of the best-known cannabis terpenes can be obtained from other botanical sources.

There is no universal winner.
Choose based on what matters most for the intended formulation.
Botanical terpenes can be particularly useful when the priorities are:
Cannabis-derived terpenes can be particularly useful when the priorities are:
The strongest terpene choice is the one that matches the required specification rather than the one with the most expensive or fashionable source description.
Whether choosing botanical terpenes or CDTs, focus on evidence.
Envisager :
Terms such as premium, laboratory grade, pure, natural and authentic are not analytical specifications by themselves.
False. Naturally extracted botanical terpenes are real plant-derived molecules.
Not when molecular identity and stereochemistry are the same.
False. Cannabinoid content depends on extraction and refinement. Testing is required.
False. Sophisticated botanical profiles can reproduce many important aspects of cannabis aroma.
False. Flavonoids are largely non-volatile compounds and are not automatically present in a volatile cannabis terpene fraction.
Not necessarily. They can be physically extracted from non-cannabis plant sources.
This has not been established as a general scientific rule.
Price reflects supply and manufacturing factors, not guaranteed analytical or sensory superiority.
False. The 0.2% figure relates to the industrial hemp cultivation framework and is not a universal finished-product exemption.
Botanical terpenes are obtained from non-cannabis plants and are commonly blended into defined aroma profiles. Cannabis-derived terpenes are recovered directly from cannabis plant material and can preserve a naturally occurring cannabis volatile fingerprint.
BDT usually means botanical-derived terpene. It describes terpene ingredients obtained from non-cannabis botanical sources such as citrus, conifers, herbs, flowers or spices.
CDT means cannabis-derived terpene. It describes aromatic compounds recovered directly from cannabis plant material rather than reconstructed entirely from non-cannabis botanical ingredients.
No. Naturally derived botanical terpenes are genuine plant molecules. A limonene molecule extracted from citrus can be chemically identical to the same limonene molecule occurring in cannabis.
Not necessarily. Botanical terpenes are commonly obtained from natural plant materials. Synthetic terpenes are produced using chemical synthesis and are a separate manufacturing category.
Yes, genuine CDTs originate directly from cannabis plant material. They still undergo extraction, separation and potentially further refinement before becoming a commercial ingredient.
Individual molecules can be. Limonene, myrcene, pinene and beta-caryophyllene do not become different chemical compounds merely because they were produced by a different plant. The complete aromatic profile surrounding those molecules can differ substantially.
A CDT can retain a wider native mixture of major terpenes, minor terpenes and other low-concentration cannabis volatiles. Those compounds and their natural ratios can create greater cultivar-specific aromatic complexity.
Neither is universally better. CDTs can offer direct cannabis source authenticity, while botanical profiles can offer greater consistency, scalability, formulation control and generally lower cost.
Botanical profiles can normally be standardised very tightly because individual ingredients are combined according to a fixed formula. Natural CDT batches can vary with genetics, cultivation, harvest and extraction conditions.
A well-produced CDT often has an advantage when the aim is to preserve the native aroma of a specific cannabis source. Sophisticated botanical profiles can nevertheless recreate highly convincing strain-inspired aromas.
A genuine botanical profile made exclusively from non-cannabis ingredients has no inherent cannabis cannabinoid source. Appropriate manufacturing quality controls and supplier documentation should still be used.
They can, depending on the extraction and refinement process. THC is not a terpene, but cannabis-derived aromatic fractions can contain cannabinoid carryover. Analytical testing is required to establish the composition of a specific batch.
Terpene molecules do not produce conventional THC intoxication. However, a cannabis-derived terpene material may contain cannabinoids if they have not been adequately separated, so the complete product composition matters.
Standard cannabis drug tests do not normally target terpene molecules. The relevant concern is whether the CDT product also contains THC or related cannabinoids.
Live resin terpenes are a type of cannabis-derived aromatic material made from fresh-frozen cannabis. Not every CDT is a live resin terpene because cannabis-derived terpenes can also be produced from dried or cured material using other extraction methods.
Choose according to the objective. BDTs are particularly useful for consistent, scalable and adjustable formulations. CDTs are particularly useful when authentic cannabis botanical origin and native aromatic complexity are the priority.
They can be, particularly when a recovery process preserves numerous minor native volatiles. However, complexity depends on the actual extraction and formulation. A sophisticated botanical profile can also contain many individual compounds.
Not automatically. Flavonoids are a separate, generally non-volatile class of plant compounds. A volatile CDT fraction should not be assumed to contain significant flavonoids unless analytical data demonstrate their presence.
CDT production can involve more expensive cannabis biomass, lower aromatic yields, specialist extraction equipment, additional regulatory considerations, testing and controlled storage. The exact price difference varies between suppliers and processes.
Source alone does not establish safety. Each concentrated terpene material should be assessed using its composition, hazard information, purity, contaminants, intended application and supplier documentation. Botanical sourcing does simplify the specific issue of cannabis cannabinoid carryover.
Either category can be highly purified. Purity is a property of the specific ingredient and manufacturing process rather than an automatic feature of botanical or cannabis origin.
Yes. Major and minor botanical terpene ingredients can be combined in controlled ratios to recreate many characteristics associated with cannabis cultivar aromas. Reproducing every trace volatile found in a specific cannabis harvest is more difficult.
Compatible terpene ingredients can potentially be combined where the technical documentation and intended application support the formulation. This can allow a native cannabis profile to be adjusted using selected botanical components.
Many common cannabis terpenes occur widely elsewhere in nature. Examples include limonene in citrus, myrcene in hops and lemongrass, pinene in conifers and herbs, linalool in lavender and coriander, and beta-caryophyllene in black pepper and cloves.
Source does not change the boiling point of an identical molecule. The same limonene molecule has the same fundamental physical properties regardless of whether its source was citrus or cannabis. Complete blends can behave differently because their compositions differ.
There is not sufficient evidence to declare one source universally superior. A CDT may contain additional native compounds, but greater chemical complexity does not by itself prove a stronger physiological entourage effect.
This has not been established as a universal effect. Some individual terpene compounds have been studied in drug-delivery research, but that does not prove that BDT or CDT profiles automatically increase cannabinoid absorption.
Common terpene molecules are not controlled merely because they occur in cannabis. However, cannabis plant material and various cannabinoids are controlled. The legal position of a CDT material therefore depends on its composition and on the manufacturing, import, possession and supply activities involved.
The 0.2% figure relates to the low-THC industrial hemp cultivation framework. It is not a universal finished-product THC threshold for cannabis-derived terpene ingredients.
Both should be protected from unnecessary heat, oxygen and light and kept in suitable tightly sealed packaging according to the supplier’s storage specification. Volatility and oxidation affect terpene materials regardless of botanical source.
The fundamental difference between botanical terpenes and cannabis-derived terpenes is not that one category contains real terpene molecules and the other does not.
Both can contain the same molecules.
Limonene remains limonene. Myrcene remains myrcene. Alpha-pinene remains alpha-pinene. Beta-caryophyllene remains beta-caryophyllene.
What changes is how the complete aromatic profile is created.
Botanical-derived terpenes are typically isolated from abundant non-cannabis plant sources and combined in defined ratios. This gives formulators considerable control over aroma, consistency, scalability and cost.
Cannabis-derived terpenes begin with the cannabis plant itself. Rather than reconstructing the profile molecule by molecule, the manufacturing process attempts to recover part of the aromatic fingerprint produced naturally by a particular cultivar or harvest.
This can include major terpenes alongside minor volatile compounds that contribute disproportionately to authentic cannabis aroma.
That native complexity is one of the principal attractions of CDT.
It also introduces natural batch variation and requires additional attention to cannabinoid carryover, source documentation and UK controlled-drug requirements.
Neither category should be described as universally superior.
Botanical terpenes are particularly strong where repeatability, precise formulation and scalable supply matter most.
Cannabis-derived terpenes are particularly strong where authentic cannabis origin and native cultivar-specific aroma are the priority.
Live resin terpenes take the CDT concept further by beginning with fresh-frozen cannabis in an attempt to preserve more of the volatile chemistry present close to harvest.
The most useful way to choose is therefore not to ask which source is simply “better”, but what chemical and sensory characteristics the finished formulation actually needs.

This article is provided for educational purposes and discusses terpene chemistry, aromatic formulation and current UK regulatory context. It is not legal advice. Concentrated terpene materials should be handled according to their technical and safety documentation, and cannabis-derived ingredients should be appropriately assessed for cannabinoid content and regulatory status.
