Abstract: A new bioactive allelochemical 1, m.p. 235-36°C, m.f. C34H42O20, [M]+ 770 (FABMS), has been isolated from methanolic extract of the seeds of Cassia absus Linn. alongwith two known compounds 3, 5, 7, 4′-tetrahydroxy-2′, 5′-dimethoxy flavone and Luteolin. The structure of a new compound has been characterized as 5, 7, 4′-trihydroxy-8,3′-dimethoxyflavone-5-O-α--rhamnopyranosyl-7-O-β--xylopyranosyl-(1→4)-O-β--galacto­­pyranoside by various colour reactions, spectral analysis and chemical degradations. All the secondary plant metabolites are called allelochemicals.
