A new flavone glycoside: 5,7,3',4'-tetrahydroxy-3-methoxy flavone-7-O-beta-D-galactopyranosyl-(1-->4)-O-beta-D-glucopyranoside from the stem of Acacia catechu Willd.
A new bio-active flavone glycoside, m.p. C28H32O17, mp 283-284-C, M-640 [EIMS] was isolated from the ethylacetate soluble fraction of the ethanolic extract of the stems of Acacia catechu and its structure was characterised as 5,7,3',4'-tetrahydroxy-3-methoxy flavone-7-O-beta-D-galactopyranosyl-(1-->4)-O-beta-D-glucopyranoside by various chemical degradations and spectral analyses.
