【Abstract】 AIM To study the chemical composition of Tripterygium wilfordii Hook.f. METHODS Column chromatography was used to separate the chemical constituents. UV, IR, MS, HRMS, 1HNMR , 13 CNMR (COM and OFR), 1H 1H COSY, 1H 13 C COSY, 2D NOESY and 1H 13 C COLOC were used to determine the structures of the isolated constituents. RESULTS Two sesquiterpene alkaloids were isolated and their structures were elucidated as euonine and wilfordconine on the basis of spectral evidence. CONCLUSION Wilfordconine, a new sesquiterpene alkaloid,was shown to be immunosuppressive.更多还原
