Abstract

The methanol soluble part of the concentrated ethanolic extract of the flowers of Strychnos potatorum Linn gave a flavonoidal glycoside AS-2 having molecular formula C21H20O12, m.p. 262-2630 C and (∝)D 16 ÷ 18.60 (in CHCl3), M+ = 464 (By mass spectroscopy). By chemical reactions and spectral analysis, it was identified as; 5,7,3'4'-tetrahydroxy flavone -3-O-β-D-Galactopyranoside.
