Abstract

Two new triterpenoid saponins,  named, 3-O-β-D-glucopyranosyl (1→3)-Olean-12-ene-19, 23-diol 1 and 3-O-{O-α-L-rhamno-pyranosyl-(1→3)-O-[-O-β-D-glucopyranosyl-(1→3)]-β-D-gluco-pyranosyl}-pomolic acid were isolated from the stem bark of Xeromphis nilotica through extensive chromatographic technique [TLC and CC] and their structures were elucidated on the basis of their spectral data [1D, 2D NMR and HR-ESI-MS] and chemical evidence.
