title: [Isolation and structure elucidation of cirensenosides Q and R].
abstract: Two new saponins (cirensenoside Q and R) were isolated from the leaves of Oplopanax elatus. Their structures were elucidated as follows: Q, gypsogenin 3-O-beta-glucopyranosyl-28-O-alpha-L-rhamnopyranosyl(1-->4)-beta-D- glucopyranosyl(1-->6)-beta-D-glucopyranoside; R, 3 beta-hydroxylup-20(29)-ene-23-al-28-oic acid 3-O-beta-D-glucopyranosyl-28-O-alpha-L-rhamnopyranosyl(1-->4)-beta-D- glucopyranosyl(1-->6)-beta-D-glucopyranoside, respectively.
