Abstract:
Objective To isolate and identify the components from the stem barks of Morus yunnanensis.Methods The compounds were isolated and purified by silic gel column,Sephadex LH-20,and RP-18 chromatography.Their chemical structures were elucidated on the basis of physicochemical properties and spectral data.Results Eleven compounds were isolated and identified as:mulberroside C(1),oxyresveratrol(2),2',4',7-trihydroxy-(2S)-flavone(3),norartocarpetin(4),moracin P(5),betulinic acid(6),sitosteryl 3?-glucoside 6'-O-palmitate(7),lupeol(8),betulinic acid(9),?-daucosterol(10),and ?-sitosterol(11).Conclusion All the compounds are isolated from the plant for the first time,and compound 9 shows cytotoxic activities.
