Abstract

Studies were carried out on the leaves of Cassia alata. A new isoflavone 5, 7- dihydroxy-3/, 4/-dimethoxy flavone was isolated from the leaves of Cassia alata with the help of column and thin layer chromatography using a gradient of organic solvents with increasing polarity. The compound was characterized on the basis of UV, IR, 1HNMR, 13C-NMR and Mass spectrometry.
