Terpenes are aromatic compounds produced by many plants, cannabis included. They are the reason one cultivar smells like citrus peel and another smells like pine or black pepper. If you have ever chosen a coffee or a wine by its aroma, you already know how to use them.
The guide below covers the terpenes that appear most often on the Kapn Chronic menu. Each entry describes aroma, flavour and where else the compound occurs in nature. This is aroma and flavour information only - it is not health or medical advice, and terpene content does not predict how any product will affect you.
Not every product lists terpene data. Where a producer supplies it, it appears on the product page, and you can tap any terpene there to see the same reference without leaving the page.
Limonene
Limonene is a cyclic monoterpene found as (+)/(R) and (−)/(S) enantiomers, which have different botanical distributions and odors.
Explore Limonene and the research →
- Aroma
- Citrus or pine-like, depending on the isomer
- Also found in
- Citrus oils and conifers
- In cannabis
- A limonene listing identifies a reported compound, not its enantiomer balance, perceived aroma, or a predictable effect. Direct human research linking limonene content to cannabis-product effects is lacking.
Alpha-Pinene
α-Pinene is a structural isomer of β-pinene; the two compounds differ in the position of a double bond.
Explore Alpha-Pinene and the research →
- Aroma
- Pine and resin
- Also found in
- Conifers and rosemary
- In cannabis
- α-Pinene on a label does not establish a pine-like experience or predict a product effect. Direct human research linking α-pinene content to cannabis-product effects is lacking.
Beta-Pinene
β-Pinene is a structural isomer of α-pinene; the two compounds differ in the position of a double bond.
Explore Beta-Pinene and the research →
- Aroma
- Pine and resin
- Also found in
- Conifers, including balsam fir
- In cannabis
- β-Pinene is distinct from α-pinene, and its presence alone does not establish a product aroma or predictable effect. Direct human research linking β-pinene content to cannabis-product effects is lacking.
Linalool
Linalool is an acyclic monoterpene alcohol with two naturally occurring enantiomers. The enantiomer proportions can change the fragrance, so “linalool” alone does not specify one exact scent.
Explore Linalool and the research →
- Aroma
- Floral and woody
- Also found in
- Lavender and basil
- In cannabis
- Linalool content does not specify the enantiomer ratio, sensory experience, or likely response. Direct human research linking linalool content to cannabis-product effects is lacking.
Beta-Caryophyllene
“Caryophyllene” commonly refers to β-caryophyllene, especially the plant-predominant (E) isomer. It is distinct from α-caryophyllene (α-humulene).
Explore Beta-Caryophyllene and the research →
- Aroma
- Woody and spicy
- Also found in
- Black pepper and cinnamon
- In cannabis
- A product listing β-caryophyllene does not establish receptor activity or a predictable product experience. Isolated-compound findings cannot be applied to a whole cannabis product.
Myrcene
Myrcene, also called β-myrcene, is an acyclic monoterpene.
Explore Myrcene and the research →
- Aroma
- Herbaceous and resinous
- Also found in
- Hops and cannabis
- In cannabis
- A myrcene result does not predict relaxation, sedation, or a particular aroma in a cannabis product. Direct human research linking myrcene content to cannabis-product effects is lacking.
Humulene
Humulene, also called α-humulene or α-caryophyllene, is an open-ring sesquiterpene distinct from β-caryophyllene.
Explore Humulene and the research →
- Aroma
- Hops contain humulene; their aroma is a mixture
- Also found in
- Hops and ginseng root
- In cannabis
- A label reporting humulene identifies a compound; its presence alone does not establish a cannabis product’s aroma or effects.
Terpinolene
Terpinolene is a monoterpene detected in volatile profiles of plant material.
Explore Terpinolene and the research →
- Aroma
- A distinct aroma is not established by the cited plant studies
- Also found in
- Pine leaves
- In cannabis
- Terpinolene on a product label does not establish a particular aroma or predict how the product will feel.
Eucalyptol
Eucalyptol, also called 1,8-cineole, is a cyclic monoterpene ether.
Explore Eucalyptol and the research →
- Aroma
- Fresh and camphor-like
- Also found in
- Eucalyptus leaves and basil
- In cannabis
- A product label or aroma profile cannot predict the product's experience. If present, eucalyptol may be one contributor among many volatile compounds, but presence alone does not predict the product's aroma.
Ocimene
Ocimene refers to a group of acyclic monoterpene isomers; β-ocimene is one member of that group.
Explore Ocimene and the research →
- Aroma
- Sweet and herbal
- Also found in
- Alpinia and basil species
- In cannabis
- Do not infer an effect from ocimene's presence. No direct human research on cannabis products containing ocimene was identified; product aroma also depends on the full volatile mixture and processing.
Terpineol
Terpineol names several related monoterpene alcohol isomers, including α-terpineol.
Explore Terpineol and the research →
- Aroma
- Alpha-terpineol is described as lilac-like
- Also found in
- Plant essential oils
- In cannabis
- A cannabis product's terpene listing cannot be used to predict the product's experience. No direct human research on cannabis products containing terpineol was identified.
Nerolidol
Nerolidol is a sesquiterpene alcohol that occurs as cis and trans geometric isomers; the tested isomer or mixture varies by study.
Explore Nerolidol and the research →
- Aroma
- Floral
- Also found in
- Some plant essential oils
- In cannabis
- Nerolidol on a terpene list does not establish that a product will reproduce mouse-study behavior. Aroma depends on the product’s volatile mixture and concentrations.
Bisabolol
This entry concerns α-bisabolol, a sesquiterpene alcohol. It is distinct from bisabolol oxides, which are separate constituents sometimes abundant in chamomile oil.
Explore Bisabolol and the research →
- Aroma
- A standalone aroma has not been established here
- Also found in
- Certain chamomile chemotypes and candeia
- In cannabis
- A report of bisabolol in cannabis identifies a constituent; it does not establish a floral aroma or show that the isolated cell-study result applies to the product.
Farnesene names a family of sesquiterpene isomers. The apple evidence concerns (E,E)-α-farnesene specifically; other farnesene isomers are distinct compounds.
Explore Farnesene and the research →
- Aroma
- Alpha-farnesene occurs among apple aroma compounds
- Also found in
- Apple fruit (specifically alpha-farnesene)
- In cannabis
- A cannabis-product listing cannot predict an orchard-fruit aroma or an effect. Terpene presence alone does not give the product’s concentration or complete volatile profile.
Guaiol is a guaiane sesquiterpene alcohol; the cited cell research specifically tested (-)-guaiol.
Explore Guaiol and the research →
- Aroma
- A standalone aroma has not been verified here
- Also found in
- Reported in some medicinal plants
- In cannabis
- No direct human research on cannabis products containing guaiol was identified. Presence in a product does not establish an effect or allow a predictable experience to be inferred.
Germacrene names a group of related sesquiterpenes; germacrene D is one member of the group.
Explore Germacrene and the research →
- Aroma
- A standalone aroma has not been verified here
- Also found in
- Bursera leaves (specifically germacrene D)
- In cannabis
- If a product analysis identifies germacrene D, that reports composition only. It does not predict an effect; an unspecified “germacrene” label also does not identify the particular germacrene isomer.
No. Terpenes describe aroma and flavour. They are not a measure of potency, and they are reported separately from THC and CBD content.
Because terpenes occur in combination. A cultivar listing limonene and one listing limonene with caryophyllene and linalool will read quite differently, in the same way two citrus perfumes differ.
Terpene data comes from the producer. Where it has not been supplied we leave the section off rather than estimate it. Accessories and non-cannabis products never carry terpene data.
