摘　　要：从萝蘼科植物大叶牛奶菜(Marsdenia koi Tsiang)的具有抗生育活性的甲醇提取物中,用硅胶层析及反相层析等方法分得一种孕甾甙,经波谱(IR,~1H-NMR,^(13)C-NMR,FAB-MS)分析及其水解产物与标准品对照,确定为一新孕甾甙,命名为大叶牛奶菜甙丙(marsdekoiside C)A pregnane glycoside ester was isolated from Marsdenia koi Tsiang by column chromatography. The structure was identified on the basis of IR, ~1H - NMR,^(13)C - NM R and FAB - MS. It is a new compound obtained from this plant for the first time and named as marsdekoiside C.
