Abstract

Two new C21 steroidal glycosides were isolated from Cynanchum otophyllum Schneid. Their structures were elucidated as qinyangshengenin-3-O-β-d-digitoxopyranoside (1) and rostratamine-3-O-β-d-cymaropyranosyl-(1 → 4)-β-d-digitoxopyranoside (2) on the basis of chemical and spectroscopic methods, including 1D and 2D NMR experiments.

Abstract

Two new C21 steroidal glycosides were isolated from Cynanchum wallichii Wight. Their structures were elucidated as caudatin-3-O-β-d-glucopyranosyl-(1 → 4)-β-d-oleandropyranosyl-(1 → 4)-β-d-cymaropyranosyl-(1 → 4)-β-d-digitoxopyranoside (1) and caudatin-3-O-β-d-glucopyranosyl-(1 → 4)-β-d-cymaropyranosyl-(1 → 4)-β-d-oleandropyranosyl-(1 → 4)-β-d-cymaropyranosyl-(1 → 4)-β-d-digitoxopyranoside (2) by spectroscopic methods including 1D and 2D NMR experiments.
