New oleanene-type triterpene saponins from Pueraria peduncularis.
Two new oleanane-type triterpene saponins named pedunsaponins B (2) and C (3) were isolated from the roots of Pueraria peduncularis. Their structures were determined to be 3-O-(6-O-methyl)-beta-glucuronopyranosyl-3beta,15alpha-dihydroxyolean-12-en-16-one (2), and 3-O-beta-glucopyranosyl-(1 --> 3)-beta-glucuronopyranosyl-3beta,15alpha-dihydroxyoleana-12-en-16-one (3), on the basis of spectroscopic evidence.
