          Abstract

          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 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-galactopyranosyl-(1-->2) -beta-D-glucuronopyranosyl kudzusapogenol B (1), 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-galactopyranosyl-(1-->2) -beta-D-glucuronopyranosyl sophoradiol 22-O-acetate (2) and 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-galactopyranosyl-(1-->2) -beta-D-glucuronopyranosyl soyasapogenol B 22-O-acetate (3), respectively.
