A Flavone from the Leaves of Cassia Alata

摘要

Studies were carried out on the leaves of Cassia alata. A flavone 3,5,7,4 Setrahy-droxy 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, 1H-NMR, 13C-NMR and Mass spectrometry.
