摘要
Three clerodane diterpenolds, 8S-kolavic acid 18-methyl ester (1), 8S-kolavic acid 15-methyl ester (2) and 8S-kolavenol (3) were isolated from the acetone extract of the stem bark of Entada abyssinica along with trans-communic acid (4) and 1-octacosanol. Their structures were established mainly based on ID (H-1, C-13 and DEPT) and 2D (H-1-H-1 COSY, HSQC and HMBC) NMR experiments. Compound 1, described here for the first time, showed strong antimicrobial and moderate antileishmanial activities.
