Two new oleanane-type triterpenoid saponins, kakkasaponin II (1) and kakkasaponin III (2), were isolated from the methanol extract of the flowers of Pueraria thomsonii (Leguminosae), together with seven known oleanane-type triterpenoid saponins, phaseoside IV (3), sophoradiol monoglucuronide (4),
From the root of Pueraria thomsonii (Leguminosae), three new oleanane-type triterpene glycosides, named kudzusaponin B1, acetyl-kaikasaponin III and acetyl-soyasaponin I were isolated, together with soyasaponin I (4) and subproside V (5). Their structures were determined to be
The anticomplementary properties of kaikasaponin III (4) and soyasaponin I (8) from Pueraria lobata and their hydrolytic analogs were investigated in vitro. Diglycosidic saponins [kaikasaponin I (3), soyasaponin III (7)] showed most potent anticomplementary activities, followed by monoglycosidic
