摘要：
Three new steroidal glycosides, cyanoauriculosides F, G and H (1-3), were isolated from the roots of Cynanchum auriculatum (Asclepiadaceae) along with two known steroidal derivatives. On the basis of spectroscopic analysis and chemical methods, their structures were identified as 20-O-acetyl-8,14-seco-penupogenin-8-one 3-O-alpha-L-cymaropyranosyl-(1-->4)-beta-D-cymaropyranosyl-(1-->4)-alpha-L-diginopyranosyl-(1-->4)-beta-D-cymaropyranoside (1), 2',3'-Z-gagaminine 3-O-alpha-L-cymaropyranosyl-(1-->4)-beta-D-cymaropyranosyl-(1-->4)-alpha-L-diginopyranosyl-(1-->4)-beta-D-cymaropyranoside (2), 17-O-acetyl-kidjoranin 3-O-alpha-L-cymaropyranosyl-(1-->4)-beta-D-cymaropyranosyl-(1-->4)-alpha-L-cymaropyranosyl-(1-->4)-beta-D-digitoxopyranosyl-(1-->4)-beta-D-digitoxopyranoside (3), gagaminine 3-O-alpha-L-cymaropyranosyl-(1-->4)-beta-D-cymaropyranosyl-(1-->4)-alpha-L-digino-pyranosyl-(1-->4)-beta-D-cymaropyranoside (4) and wilfoside D1N (5).
