Isolation and investigation of antimicrobial effect of 3,4,3'-tri-O-methylflavellagic acid and its glucoside from Anogeissus leocarpus

Abstract

3,4,3'-Tri-O-methylflavellagic acid and its glucoside (reported for the first time) were isolated from Anogeissus leocarpus. These compounds were analysed by GC-MS, IR, 1D and 2D-NMR, and also as acetates. Antimicrobial effect of the glucoside on S. aureus, E. coli, Ps. aeruginosa and C. albicans show that it possesses growth inhibitory effect at various concentrations.
