摘 要 ：从晚香玉(Polianthes tuberosa L.)球茎中分离到3个胆甾烷类配糖体。经波谱分析鉴定,其中1个为新的胆甾烷类配糖体，即(22S)-胆甾烷-5-烯-1β,3β,16β,22,25-五醇1-O-β-D-葡萄吡喃糖基-16-O-β-D-芹菜呋喃糖苷。

Abstract:A new cholestane glycoside, (22S)-cholest-5-en-1β,3β,16β,22,25-pentaol 1-0-β-D-glucopyranosyl-16-O-β-D-apiofuranoside, together with two known cholestane glycosides were isolated from the tubers of Polianthes tuberosa. Their structures were elucidated on the basis of spectroscopic data.
