ISOLATION AND CHARACTERIZATION OF PHYTOCHEMICALS FROM STEM BARK OF CASSIA FISTULA LINN

Abstract

Different parts of the plant Cassia fistula Linn. are used in traditional medicine system due to their bioactive compounds. Phytochemical examination 
on the methanolic extract of Cassia fistula Linn. stem bark led to the isolation of 1,8-Dihydroxy-3-methylanthraquinone (A), Lupeol (B), β-sitosterol 
(C) and 1,8-dihydroxy-3-carboxylicanthraquinone (D) bioactive compounds. The structure of these compounds was elucidated on the basis of different 
type of spectroscopic techniques i.e 1H NMR, 13C NMR, IR and MS.
