A Flavone from the Leaves of Cassia Alata

Abstract

Studies were carried out on the leaves of Cassia alata. A flavone 3,5,7,4´-tetrahydroxy flavone was isolated as a new source 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.
