To study the components in aerial part of Siegesbeckia pubescens.
The compounds were isolated and purified by silica gel, sephadex LH-20 and other column chromatography. Structures were elucidated by spectroscopic methods.
Four compounds were isolated from S. pubescens and were characterized as dimethyl-21-ethenetylene-darutigenol-3-O-beta-D-glucopyranosid (1), darutigenol (2), darutoside (3), stigmaster-3-O-beta-D-glucopyranosid (4).
Compound 1 is a new compound.
研究毛梗稀莶地上部分的成分。
