Abstract

A new phenolic glucoside gallate, vanillic acid 4-O-?-D-(6'-O-galloyl) glucopyranoside (I) was isolated from the bark of Terminalia macroptera Guill.et Perr., together with 3,3',4'-tri-O-methylellagic acid and two triterpene glucopyranosyl esters, 24-deoxy-sericoside and chebuloside II. Compds. 2-4, not described previously for this plant, showed antimicrobial activities against Bacillus subtilis, while 3 and 4 possessed hemolytic properties. In both assays 1 was found to be inactive.
