A chemotaxonomic analysis of terpenoid variation in Cannabis

摘要: To determine whether the terpenoid composition of essential oil Cannabis is useful for chemotaxonomic discrimination, extracts pistillate inflorescences 162 greenhouse-grown plants diverse origin were analyzed by gas chromatography. Peak area ratios 48 compounds subjected to multivariate analysis and results interpreted with respect geographic taxonomic affiliation. A canonical in which pre-assigned C. sativa or indica based on previous genetic, morphological, studies resulted 91% correct assignment their species. scatterplot first two principal component axes shows that accessions from Afghanistan assigned wide-leaflet drug biotype (an infraspecific taxon unspecified rank) group apart other putative taxa. The these usually had relatively high guaiol, isomers eudesmol, unidentified compounds. Plants narrow-leaflet tended have trans-β-farnesene. Cultivars biotypes may exhibit distinctive medicinal properties due significant differences composition.
