One new and three known steroidal glycosides were isolated from the ethyl acetate extract of the roots of Cynanchum wallichii Wight. Their structures were characterized as qinyangshengenin-3-O-α-Lcymaropyranosyl-(1→4)-β-D-oleandropyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-Ddigitoxopyranoside (1), otophylloside A (2), otophylloside B (3), and cynanauriculoside A (4).
