摘要: The major metabolites of Diopsyros melanoxylon viz. amyrins and ursolic acid their lipophilic 3-O-fatty ester chains (C12—C18), which are synthesized now under mild esterification conditions in excellent yields (80—95%), were evaluated for antimicrobial activity against a series Gram positive negative bacteria. Significantly these compounds found to exhibit potent bacteria Pseudomonas syringae (ATCC #13457) fairly good bacteria, Bacillus sphaericus #14577) subtilis #6051).
