Abstract
Four novel triterpenoid saponins have been isolated from Gypsophila ca pillaris. Three were monodesmosidic: 3 beta-hydroxyolean-12-en-23,28-d ioic acid 28-O-[beta-D-glucopyranosyl-(1 --> 3)-beta-D-glucopyranosyl- (1 --> 2)][beta-D-galactopyranosyl(1 --> 6)]beta-D-glucopyranoside, 3 beta-hydroxyolean-12-en-23-oxo-28-oic acid 28-O-[beta-D-glucopyranosyl -(1 --> 2)-beta-D-galactopyranosyl-(1 --> 3)][beta-D-glucopyranosyl-(1 --> 6)] beta-D-galactopyranoside, 3 beta-hydroxyolean-12- en-23,28-di oic acid 28-O-[beta-D-glucopyranosyl-(1 --> 2)-beta-D-galactopyranosyl -(1 --> 3)] [beta-D-glucopyranosyl(1 --> 6)]beta-D-galactopyranoside. The fourth was bisdesmosidic: 3 beta-hydroxyolean-12-en-23,28-dioic ac id eta-D-glucopyranosyl-28-O-[beta-D-glucopyranosyl-( 1 --> 2)-beta-D- galactopyranosyl-(1 --> 3)][beta-D-glucopyranosyl-(1 --> 6)] beta-D-ga lactopyranoside. The structures of the compounds were elucidated by 1D and 2D NMR techniques and from other spectroscopic evidence.
