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), $\beta$-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.
