Abstract:Eigth compounds were isolated from the ethanol extraction of Cassia mimosoides Linn. using by menthod of silica gel column and chromatograghy separation. On the basis of spectral data, they were identified as emodin (1), luteolin (2), 1,3-benzenediol (3), oleanolic acid (4), (R)-artabotriol (5), α-L-rhamnose (6), β-sitosterol (7) and daucosterol (8). All compounds except 1 were isolated from this plant for the first time, and compound 5 was obtained from Leguminosae for the first time.
