Triterpenoid glycosides from Stauntonia chinensis.
A new bidesmoside triterpenoid saponin, named stauntoside C1 (1), along with three known saponins (2-4) was isolated from Stauntonia chinensis DC. (Lardizabalaceae). Their structures were established by means of spectral and chemical methods as 3-O-beta-D-xylopyranosyl-(1 --> 2)-O-beta-D-xylopyranosyl-(1 --> 3)-O-alpha-L-rhamnopyranosyl-(1 --> 2)-alpha-L-arabinopyranosyl oleanolic acid 28-O-alpha-L-rhamnopyranosyl-(1 --> 4)-beta-D-glucopyranosyl-(1 --> 6)-beta-D-glucopyranosyl ester (1), scabiosaponin E (2), sieboldianoside B (3), and kizutasaponin K(12) (4).
