Cannabis Compound Identification
Common NameCannabistilbene IIb
DescriptionCannabistilbene IIb is one of 3 cannabistilbenes (the others being cannabistilbene IIa and cannabistilbene I) found in Cannabis savita. It belongs to the class of organic compounds known as stilbenes. These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6) are derived from a common phenylpropene (C6-C3) skeleton building block. Cannabistilbene IIb belongs more formally to the class of the dihydrostilbenes. The introduction of one or more hydroxyl groups to a phenyl ring leads to stilbenoids. Stilbenoids were first detected and isolated from the stems of cannabis plants in 1982, from cannabis leaves in 1978 and from cannabis resin in 1986 ( Ref:DOI ). Cannabistilbene IIb holds two hydroxyl groups (one is methylated) in ring A, both in a meta arrangement in relation to the C2 moiety. On the other hand, ring B holds one hydroxyl group in position 2 and two methoxyl groups in positions 3 and 4. Cannabistilbene IIb is a neutral, hydrophobic molecule that is insoluble in water. Cannabistilbene IIb is one of the non-cannabinoid phenolic compounds that are known to occur in the Cannabis plants (PMID: 28799497 ).
