Abstract:
A new flavonol glycoside m.f. C29H34O16, m.p. 260-262 degrees C, [M]+ 638 (EIMS) was separated from the chloroform soluble fraction of the concentrated 80% methanolic extract of the seeds of Abrus precatorius (Linn). It was characterised as a new biologically active flavonol glycoside 7,3',5'-trimethoxy-4'-hydroxy flavone-3-O-beta-D-galactosyl-(l --> 4)-alpha-L-xyloside (1) by several colour reactions, spectral analysis and chemical degradations.
