从毛旋毛虫(Trichilia claussenii)茎的甲醇提取物中分离得到3种新的甾体化合物:2 α,3 α-二羟基雄甾烷-16-酮2 β,19-半缩酮,2 α,3 β-二羟基雄甾烷-16-酮2 β,19-半缩酮,2 β,3 β-二羟基雄甾烷-16-酮。还分离出两种已知的甾体2 β,3 β,4 β-三羟基吡喃-16-酮、2 α,3 α,4 β-三羟基吡喃-16-酮以及谷甾醇和豆甾醇β-O-D-吡喃葡萄糖苷的混合物。分离的化合物的结构确定的光谱分析的基础上。(C)爱思唯尔科技有限公司版权所有。
The methanol extract of stems of Trichilia claussenii yielded three new steroids: 2 alpha,3 alpha-dihydroxyandrostan-16-one 2 beta,19-hemiketal, 2 alpha,3 beta-dihydroxypregnan-16-one 2 beta,19-hemiketal, 2 beta,3 beta-dihydroxypregnan-16-one. Two known steroids 2 beta,3 beta,4 beta-trihydroxypregnan-16-one, 2 alpha,3 alpha,4 beta-trihydroxypregnan-16-one and a mixture of sitosterol and stigmasterol beta-O-D-glucopyranosides were also isolated. The structures of the isolated compounds were determined on the basis of spectroscopic analysis. (C) Elsevier Science Ltd. All rights reserved.
