从雪莲根中分离得到两个新的多羟基孕烷糖苷，分别为蛇床子苷I-J和三个已知的甾体化合物，即脱乙酰化偏多环素、肌球蛋白和含铁血黄素。它们的结构通过广泛的波谱方法确定，特别是2D核磁共振技术)和酸催化的水解法。
Two new polyhydroxypregnane glycosides, namely cynotophyllosides I-J, were isolated from the roots of Cynan-chum otophyllum, together with three known steroids, namely deacetylmetaplexigenin, sarcostin and hemoside. Their structures were established by extensive spectroscopic methods especially 2D NMR techniques) and acid-catalysed hydrolysis.
