摘要：

The air-dried stems and ripe fruit of Drypetes inaequalis Hutch. (Euphorbiaceae) were studied. Four triterpene derivatives, characterized as lup-20(29)-en-3 beta,6 alpha-diol, 3 beta-acetoxylup-20(29)-en-6 alpha-ol. 3 beta-caffeoyloxylup-20(29)-en-6 alpha-ol and 28-beta D-glucopyranosyl-30-methyl 3 beta-hydroxyolean-12-en-28,30-dioate along with 10 known compounds were isolated from the whole stems. One triterpene. characterized as 3 alpha-hydroxyfriedelan-25-al along with six known compounds were isolated from the ripe fruit. Their structures were established on the basis of spectroscopic analysis and chemical evidence. The triterpenes were tested for antimicrobial activity against some Gram-positive and Gram-negative bacteria, and two of them appeared to be modestly active. (C) 2009 Elsevier Ltd.
