[Isolation and structure of wilfordlonging from Tripterygium wilfordii Hook. f].
OBJECTIVE
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, 13CNMR (COM and OFR), 1H-1H COSY, 1H-13C 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.


CONCLUSIONS
Wilfordclonine is a new sesquiterpene alkaloid.
