title: Isolation of triterpene saponins from Gypsophila capillaris.
abstract: Four novel triterpenoid saponins have been isolated from Gypsophila capillaris. Three were monodesmosidic: 3 beta-hydroxyolean-12-en-23,28-dioic 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-dioic 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 acid 23-O-beta-D-glucopyranosyl-28-O-[beta-D-glucopyranosyl-(1-->2)-beta-D- galactopyranosyl-(1-->3)][beta-D-glucopyranosyl-(1-->6)]beta-D- galactopyranoside. The structures of the compounds were elucidated by 1D and 2D NMR techniques and from other spectroscopic evidence.
