Two major triterpenoid saponins, named saponariosides A and B, were isolated from the whole plants of Saponaria officinalis and were respectively defined to be 3-O-beta-D-galactopyranosyl-(1-->2)-[beta-D-xylopyranosyl-(1-->3)]-be ta-D-glucuronopyranosyl quillaic acid 28-O-beta-D-xylopyranosyl-(1-->3)-beta-D-xylopyranosyl-(1-->4)-alpha- L-rhamnopyranosyl-(1-->2)-[beta-D-xylopyranosyl-(1-->3)-beta-D-4-O-ac etylquinovopyranosyl-(1-->4)]-beta-D-fucopyranoside (1); 3-O-beta-D-galactopyranosyl-(1-->2)-[beta-D-xylopyranosyl-(1-->3)]-be ta-D-glucuronopyranosyl quillaic acid 28-O-beta-D-xylopyranosyl-(1-->3)-beta-D-xylopyranosyl-(1-->4)-alpha- L-rhamnopyranosyl-(1-->2)-[beta-D-4-O-acetylquinovopyranosyl-(1-->4)] -beta-D-fucopyranoside (2). Their structures were established on the basis of extensive NMR (DEPT, DQF-COSY, HOHAHA, HETCOR, HMBC, and NOESY) and MS studies as well as chemical degradation.
