雷公藤倍半萜生物碱的研究

目的　研究雷公藤(Tripterygium wilfordii Hook.f.)的化学成分。方法　应用各种色谱技术进行分离纯化，用UV，IR，MS，HRMS，¹HNMR，¹³CNMR(COM和OFR)，¹H-¹HCOSY，¹H-¹³CCOSY，2D-NOESY，¹H-¹³CCOLOC鉴定化合物。并进行初步的药理实验。结果　分离并鉴定了2个生物碱：euonine(I)和雷公藤康碱(IIwilfordconine)。结论　II为一种新的倍半萜生物碱，药理实验证明该生物碱有免疫抑制活性，并对白血病细胞有抑制作用。

STUDY OF SESQUITERPENE ALKALOIDS FROM TRIPTERYGIUM WILFORDII HOOK.F.

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, 13CNMR (COM and OFR), 1H-1H COSY, 1H-13C COSY, 2D-NOESY and 1H-13C 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.
