Non-cannabinoid constituents from a high potency Cannabis sativa variety

Abstract

As part of our program to study the phytochemistry of high potency Cannabis sativa L. [1,2], seven new non-cannabinoid constituents were isolated, namely 5-acetoxy-6-geranyl-3-n-pentyl-1,4-benzoquinone (1), 4,5-dihydroxy-2,3,6-trimethoxy-9,10-dihydrophenanthrene (2), 4-hydroxy-2,3,6,7-tetramethoxy-9,10-dihydrophenanthrene (3), 4,7-dimethoxy-1,2,5-trihydroxyphenanthrene (4), α-cannabispiranol (5), cannflavin C (6) and β-sitosteryl-3-O-β-D-glucopyranoside-2'-O-palmitate (7). In addition, four known compounds, chrysoeriol (8), 6-prenyl-apigenin (9), cannflavin A (10) and β-acetyl cannabispiranol (11), were identified, with 8 and 9 being reported for the first time form cannabis. The antimicrobial, antileishmanial, antimalarial and anti-oxidant activities of these isolates were evaluated.
