Phytochemical and biological investigation of the leaves of Cassia petersiana afforded four compounds including a new dihydroanthracenone (1), two known chromones (2,3), in addition to stigmasterol glucoside (4). The work was guided by the antisalmonellal activity of the extract and fractions. Compound 4 was found to be the active principle. The structures of the compounds were determined by combination of spectroscopic techniques, including 1H, 13C, DEPT, COSY, HMQC, HMBC, MS and IR.
