Abstract:
AIM:To study the chemical constitutes of Celastrus orbiculatus Thunb. METHODS:Root of celastmus orbiculatus was macerated with cool ethanol to obtain the extract under the vaccum drying processing,extract obtained was extracted respectively by petroleum ester and ethyl acetate. Final extracts were purified by Silicagel column and analyzed by UV,IR,Ms and NMR to identify the chemical structural formula. RESULTS:Seven compounds were isolated from Celastrus orbiculatus Thunb,from which five constituents came from petroleum ester extract,and identified as sugiol (1),pristimerin (2),?-sitosterol (3),celastrol (4),from which two constituents came from ethyl acetate extract,salapermic acid(5),benzoic acid (6) and daucosterol (7),respectively. CONCLUSION:Compounds 1,5 were obtained from the plant for the first time.
