AbstractSix new pregnane glycosides with an acyl at C-12 and a straight sugar chain at C-3, namely otophyllosides H-M (1-6), were isolated from the roots of Cynanchum otophyllum (Asclepiadaceae) collected from Eryuan County in Yunnan province of China. Their structures were characterized to be qingyangshengenin 3-0-beta-D-glucopyranosyl-(1 -> 4)-beta -D-glucopyranosyl-(1 -> 4)-beta-D-cymaropyranosyl-(1 -> 4)-beta-D-cymaropyranosyl-(l -> 4)-beta-D-digitoxopyranoside (1), qingyangshengenin 3-0-beta-D-glucopyranosyl-(1 -> 4)-beta-D-cymaropyranosyl-(1 - 4)-0-D-cymaropyranosyI-(1 - 4)-p-D-digitoxopyranoside (2), qingyangshengenin 3-0-beta-D-glucopyranosyl-(1 -> 4)-beta-D-cymaropyranosyl-(1 -> 4)- beta-D-oleandropyranosyl-(1 -> 4)-beta-D-cymaropyranosyl-(1 -> 4)-beta-D-digitoxopyranoside (3), qingyangshengenin 3-0-beta-D-glucopyranosyl-(1 -> 4)-beta-D-thevetopyranosyl-(1 -> 4)-beta-D-cymaropyranosyl(1 -> 4)-beta-D-digitoxopyranoside (4), caudatin 3-0-beta-D-glucopyranosyl-(1 -> 4)-beta-D-glucopyranosyl-(1 -> 4 )-beta-D-cymaropyranosyl-(1 -> 4)-beta-D-oleandropyranosyl-(1 -> 4)-beta-D-cymaropyranoside (5), caudatin 3-0-beta-D-glucopyranosyl-(1 -> 4)-beta-D-cymaropyranosyl-(1 -> 4)-beta-D-oleandropyranosyl-(1 -> 4)-beta-D-cymaropyranosyl-(1 -> 4)-beta-D-cymaropyranoside (6), respectively, on the basis of detailed spectroscopic analysis and chemical method.
