Three new halimane-type diterpenoids, crotohalimaneic acid ( 1), crotohalimoneic acid ( 2) and 12-benzoyloxycrotohalimaneic acid ( 3), were isolated from the stem bark of Croton oblongifolius Roxb. Their structures were established on the basis of spectroscopic and X-ray analysis. Compounds 1 and 2 showed non-specific strong cytotoxicity against a panel of human tumor cell lines; whereas 3 was inactive.
从长圆叶巴豆（Croton oblongifolius Roxb.）的茎皮中分离出三种新的半日花烷型二萜类化合物，巴豆半日花酸（1）、巴豆半日花酮酸（2）和12-苯甲酰氧基巴豆半日花酸（3）。它们的结构通过光谱和X射线分析得以确定。化合物1和2对一组人类肿瘤细胞系表现出非特异性的强细胞毒性；而化合物3没有活性。
