The extraction process was perfomed by ethyl acetate, followed byfractionation using Column Gravitation Chromatography and Size Exclusion Chromatography. The isolated compound was a brownish yellowpowder with melting point at215-2160C. The structure was determined by means of spectroscopy analysis UV, IR, 1H and 13C NMR. The compound was known as 2, 4, 6-trihydroxy benzophenon (1).
