摘要：

Two new C-21 steroidal glycosides, characterized with caudatin as the aglycone moiety and 2,6-dideoxy-pyranoses as component sugars, have been isolated from the roots of Cynanchum wallichii Wight. Their structures were elucidated as caudatin-3-O-beta-D-cymaropyranosyl-( 1 -> 4)-beta-D-digitoxopyranoside (1) and caudatin-3-O-beta-D-oleandropyranosyl-(1 -> 4)-beta-D-cymaropyranoside (2) by spectroscopic evidence.
