Aim:
To study the anthraquinone constituents of the stem of Cassia siamea.
Methods:
The compounds were isolated by chromatography on silica gel, MHPLC, and identified on the basis of spectral analysis including IR, EI-MS, FAB-MS, 1HNMR, 13CNMR and DEPT.
Results:
Three compounds were isolated and identified as: chrysophanol (I), chrysophanol-1-O-beta-D-glucopyranoside (II) and 1-[(beta-D-glucopyranosyl-(1-->6)-0-beta-D-glucopyranosyl) oxy]-8-hydroxyl-3-methy-9,10-anthraquinone (III).
Conclusion:
III is a new compound, II was obtained from this plant for the first time.
