AIMTo study the chemical composition of Tripterygirm wilfordii Hook. f.
METHODSColunm chromatography was used to separate the chemical constituents. UV, IR, MS, HRMS, 1HNMR, 13CNMR (COM and OFR), 1H-1H COSY, 1H-13C COSY, NOESY and COLOC spectra were used to determine the structures of the isolated constituents.
RESULTSTwo sesquiterpene alkaloids were isolated and their structures were elucidated as wilforgine and wilfordlongine on the basis of spectral evidence.
CONCLUSIONWilfordclonine is a new sesquiterpene alkaloid.
