Abstract:  Two flavonoids and two carboxylic acids have been isolated from the ethyl acetate extract of the roots. The structures of these compounds have been established as myricetin-3,3′,5′,7-tetra methyl ether 1, ampelopsin-3′,4′,5′,7-tetramethyl ether 2, plumbagic acid 3 and roseanoic acid 4 on the basis of UV, IR, 1H and 13 C NMR and mass spectrum studies. The two carboxylic acids 3 and 4 are reported here for the first time. Compounds 1 and 2 are the first report from the genus plumbago.
