title: Oleanane-triterpene saponins from Clinopodium chinense var. parviflorum.
abstract: From the whole plants of Clinopodium chinense var. parviflorum three new saponins, named clinoposaponins IX-XI, were isolated together with three known saponins and their structures elucidated from spectroscopic data and chemical evidence. Clinoposaponins IX, X and XI were identified as 13 beta,28-epoxy-16 beta,23-dihydroxyolean-11-en-3 beta-yl-beta-D- glucopyranoside,13 beta,28-epoxy-16 beta,23-dihydroxyolean-11-en-3 beta-yl-beta- D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside and 13 beta,28-epoxy-16 beta-hydroxyolean-11-en-3 beta-yl-beta-D-glucopyranosyl- (1-->2)-[beta-D-glucopyranosyl-(1-->3)]-beta-D-fucopyranoside.
