【Abstract】 AIM To study the chemical composition of Tripterygirm wilfordii Hook.f. METHODS Colunm 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, NOESY and COLOC spectra were used to determine the structures of the isolated constituents. RESULTS Two sesquiterpene alkaloids were isolated and their structures were elucidated as wilforgine and wilfordlongine on the basis of spectral evidence. CONCLUSION Wilfordclonine is a new sesquiterpene alkaloid.更多还原
