Abstract

Phytochemical investigation of a high potency variety of Cannabis sativa L. resulted in the isolation of six new metabolites, (±)-6,7-trans-epoxycannabigerolic acid (2), (±)-6,7-cis-epoxycannabigerolic acid (3), (±)-6,7-cis-epoxycannabigerol (4), (±)-6,7-trans-epoxycannabigerol (5), 5′-methyl-4-pentylbiphenyl-2,2′,6-triol (7), and 7-methoxycannabispirone (8), along with seven known compounds namely, cannabigerolic acid (1), 5′-methoxycannabigerolic acid (6), cannabispirone (9), β-cannabispiranol (10), dehydrocannabifuran (11), cannflavin B (12) and cannabigerol (13). The antimicrobial as well as the antileishmanial activities were investigated.
