Abstract

A new pregnane glycoside, marsdekoiside A was isolated from the stems of Marsdenia koi (Asclepiadaceae) and its structure was elucidated from chemical and spectral data as 12-cinnamoyl-dihydrosarcostin-3-O-methyl-6-deoxy-beta-D-allopyr ano syl-(1----4)-O-beta-D-oleandropyranosyl-(1----4)-O-beta-D-++ +cymar opyranoside.

摘要

从牛奶菜属植物（萝藦科）的茎中分离出一种新的孕甾糖苷，马氏牛奶菜苷A，并通过化学和光谱数据确定其结构为12-肉桂酰基-二氢肉珊瑚苷-3-O-甲基-6-脱氧-β-D-阿洛吡喃糖基-(1→4)-O-β-D-夹竹桃吡喃糖基-(1→4)-O-β-D- cymaropyranoside。
