Abstract

Six compounds were isolated from the leaves of Cassia alata L. (Caesalpiniaceae), including: aloe emodin (1), aloe emodin-8-O-β-glucoside (2), rhein methyl ester (3), kaempferol (4), 4-hydroxybenzoic acid (5) and phytol (6). Rhein methyl ester (3) was first isolated from the Cassia genus. Their chemical structures were elucidated by spectroscopic analysis.
