Triterpenoid Saponins from the Stem Bark of Xeromphis nilotica (Rubiaceae)
Journal Title: Journal of Medicinal and Chemical Sciences - Year 2018, Vol 1, Issue 2
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.
