The roots of Cynanchum caudatum M. (Asclepiadaceae) afforded eleven new pregnane glycosides which had cynanchogenin, caudatin, 12-O-benzoyllineolon and 12-O-benzoyldeacylmetaplexigenin as the aglycone moiety and 2,6-dideoxy-3-O-methylhexopyranoses as component sugars. The structures of these compounds were elucidated by spectroscopic methods and from chemical evidence.
徐长卿（萝藦科）的根中含有11种新的孕甾烷糖苷，其苷元部分为白前苷元、白薇苷、12-O-苯甲酰基异去氧娃儿藤醇和12-O-苯甲酰基去酰基萝藦苷元，组成糖为2,6-二脱氧-3-O-甲基己吡喃糖。通过光谱方法和化学证据阐明了这些化合物的结构。
