Anthraquinones and Other Constituents from the Stem Bark of Cassia nodosa

Abstract

Thirteen compounds including four anthraquinones were isolated from the stem bark of Cassia nodosa. Their structures were elucidated as palmitic acid, lupenone, lupeol, β-sitosterol, stigmasterol, β-sitosterol-β-D-glucoside, eicosanoic acid, ethyl cerotate, chrysophanol, physcion, 1,5-dihydroxy-3-methoxyanthraquinone, 1,5-dihydroxy-3-methoxy-7-methylanthraquinone and pinitol. All of these, except chrysophanol have been isolated for the first time from the stem bark of this plant.
