A triterpenoid saponin from Phytolacca esculenta.
A new triterpenoid saponin, 3-O-[beta-D-glucopyranosyl(1----4)-beta-D- xylopyranosyl]-28-O-beta-D-glucopyranosyl-30-methyloleanate-9(11), 12-dien- 2,3,23-trihydroxyl-28-oic acid, was isolated from the roots of Phytolacca esculenta. The structure was assigned by chemical methods and spectral analysis (1H, 13C, DEPT NMR, EIMS and FABMS) including 1H-1H COSY, 1H-13C COSY and 1H-1H NOESY.
