Abstract

Studies were carried out on the leaves of Cassia alata . An isoflavone 2, 5, 7, 4 '-tetrahydroxy isoflavone was isolated for the first time from the leaves of Cassia alata with the help of column and thin layer chromatography by using a gradient mixture of organic solvents with increasing polarity. The compound was characterized on the basis of UV, IR, and 1H -NMR, 13 C-NMR and Mass spectrometry and confirmed the compound belonged to the isoflavone series.
