摘要	HPLC analysis of the roots of Cynanchum otophyllum Scheind (Asclepiadaceae) led to the isolation of six new pregnane glycosides, specifically otophyllosides N-P (2-4) and otophyllosides Q-S (7-9), in addition to the identification of three known C-21 steroidal glycosides, otophylloside A (1), otophylloside B (5) and caudatin 3-O-beta-D-glucopyranosyl-(1 -> 4)-beta-D-oleandropyranosyl-(1 -> 4)-beta-D-cymaropyranosyl-(1 -> 4)-beta-D-cymaropyranoside (6). The structure of each glycoside was determined by detailed spectroscopic analysis and chemical methods. All compounds contain qingyangshengenin or caudatin aglycones and a straight sugar chain consisting of 4-7 hexosyl moieties with the mode of 1 -> 4 linkage. The optically isomeric monosaccharides, D- and L-cymarose, coexisted in both otophyllosides R (8) and S (9). (C) 2011 Elsevier Inc. All rights reserved.
