T. Arao et al., OLEANENE-TYPE TRITERPENE GLYCOSIDES FROM PUERARIAE RADIX .3. 3 NEW SAPONINS FROM PUERARIA-THOMSONII, Chemical and Pharmaceutical Bulletin, 44(10), 1996, pp. 1970-1972
From the root of Pueraria thomsonii (Leguminosae), three new oleanane-
type triterpene glycosides, named kudzusaponin B-1, acetyl-kaikasaponi
n III and acetyl-soyasaponin I were isolated, together with soyasaponi
n I (4) and subproside V (5), Their structures were determined to be g
alactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl kudzusapogenol B (1)
, galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl sophoradiol 22-O-
acetate (2) and galactopyranosyl-(1-->2)-beta-D-glucuronopyranosyl soy
asapogenol B 22-O-acetate (3), respectively.
