| Abstract: | 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-β-d-xylopyranosyl-(1 → 2)-O-β-d-xylopyranosyl-(1 → 3)-O-α-l-rhamnopyranosyl-(1 → 2)-α-l-arabinopyranosyl oleanolic acid 28-O-α-l-rhamnopyranosyl-(1 → 4)-β-d-glucopyranosyl-(1 → 6)-β-d-glucopyranosyl ester (1), scabiosaponin E (2), sieboldianoside B (3), and kizutasaponin K12 (4). |
