A new pregnane glycoside, marsdeoreophiside B was isolated from the stems of Marsdenia oreophila (Asclepiadeaece). The structure was elucidated by means of chemical and spectrometric analysis as 12-O-cinnamyldihydrosarcostin-3-O-beta-D-glucopyranosyl (1-->4)-O-3-O-methyl-6-deoxy-beta-D-allopyranosyl(1-->4)-O-beta-D- oleandropyranosyl (1-->4)-O-beta-D-cymaropyranoside. It showed significant antifertility activity in rats.
从牛奶菜属植物（萝藦科）峨眉牛奶菜的茎中分离出一种新的孕甾烷糖苷，即峨眉牛奶菜苷B。通过化学和光谱分析确定其结构为12 - O - 肉桂酰二氢肉珊瑚苷 - 3 - O - β - D - 吡喃葡萄糖基（1→4） - O - 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 - 磁麻吡喃糖苷。它在大鼠中显示出显著的抗生育活性。
