Cannabis Compound Identification
Common NameIndole
DescriptionIndole is an aromatic heterocyclic organic compound. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. The participation of the nitrogen electron pair in the aromatic ring means that indole is not a base, and it does not behave like a simple amine. Indole is widely distributed in nature and can be produced by a variety of bacteria. Indole occurs naturally in human feces and has an intense fecal odor. At very low concentrations, however, it has a flowery smell, and is a constituent of many flower scents (such as orange blossoms) and perfumes. Indole is formed during the combustion of cannabis and is therefore a constituent of cannabis smoke (Ref: Ref:DOI ).
