A new C21 steroidal glycoside, 5beta,6beta-epoxy-glaucogenin C-3-O-beta-D-glucopyranosyl-(1 --> 4)-beta-d-glucopyranosyl-(1 --> 4)-beta-D-cymaropyranosyl-(1 --> 4)-beta-D-oleandropyranosyl-(1 --> 4)-beta-D-oleandropyranoside, named inamoside D (1), was isolated from the MeOH extract of the roots of
Three new C(21)-steroidal glycosides presenting an unusual 13,14:14,15-disecopregnane-type skeleton, named inamosides A-C (1-3), together with two known C(21)-steroidal glycosides, were isolated from the MeOH extract of the roots of Cynanchum inamoeum (Maxim.) Loes (Asclepiadaceae). The aglycone of
