Abstract

Two new triterpene saponins (1 and 2), named bidenosides A and B, were isolated from the roots of Knautia integrifolia var. bidens. The structures were identified as 3-O-alpha-L-rhanmopyranosyl-28-O-[beta-D-allopyranosyl-(1 --> 6)-beta-D-glucopyranosyl]-pomolic acid, and 3-O-alpha-L-rhamnopyranosyl-28-O-[beta-D-allopyranosyl-(1 --> 6)-beta-D-glucopyranosyl]-oleanolic acid on the basis of spectroscopic evidence.
