| Abstract: | OBJECTIVE:To study the chemical composition seeds of Cassia obtusifolia.METHODS:Microwave benzene-sulfuric acid extraction and silica gel chromatography were used to separate and purify C.obtusifolia.The structure of it was identified according to physical and chemical properties and spectral data.RESULTS:8 compounds were isolated and identified from benzene-sulfuric acid extract of C.obtusifolia,which were rhein (1),obtusifolin(2),2-Methoxy-obtusifolin(3),aloe-emodin(4),emodin (5),aurantio-obtusin (6),chrysophanol (7) and physcion (8).Compound 1 was indentified from C.obtusifolia for the first time.CONCLUSION:The method is simple and rapid,and it can provide evidence for further study of C.obtusifolia. |
