title: Oleanene-type triterpene glycosides from puerariae radix. IV. Six new saponins from Pueraria lobata.
abstract: From Puerariae Radix, the root of Pueraria lobata (Leguminosae), six new oleanene-type triterpene glycosides, called kudzusaponins A1 (1), A2 (2), Ar (3), SA4 (5), and SB1 (6) were isolated together with kudzusaponin A3 (7), soyasaponins SA3 (8), and I (9). The structures of 1-6 were determined to be 3-O-alpha-L-rhamnopyranosyl- (1-->2)-beta-D-arabinopyranosyl-(1-->2)beta-D-glucuronopyranosy l kudzusapogenol A 22-O-beta-D-xylopyranoside, 3-O-beta- D-galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl kudzusapogenol A, 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucuronopyranosyl kudzusapogenol A, 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->2)-beta- D-glucoronopyranosyl kudzusapogenol A, 3-O-beta-D-glucuronopyranosyl[(1-->2)-beta-D-glucuronopyranosyl soyasapogenol A22-O-alpha-L-arabinopyranoside,and 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-galactopyranosyl- (1-->2)-beta- D-glucuronopyranosyl (beta-fabatriosyl) soyasapogenol B 22-O-alpha-L-arabinopyranoside, respectively.
