摘    要:目的: 研究白藜芦醇的体内代谢产物。 方法: 采用液质联用法,通过分析原型化合物及代谢产物的液相分析保留时间、二级质谱裂解数据以及紫外吸收光谱,推测单次给药白藜芦醇后的代谢产物。色谱条件:Zorbax SB-C18色谱柱(4.6 mm×250 mm,5 μm),Zorbax SB-C18 保护柱(4 mm×20 mm,5 μm),流动相(A)乙腈-(B)水梯度洗脱:0~20 min, 3%~18%A,20~40 min,18%~35%A,流速1.0 mL·min-1,检测波长320 nm,柱温30℃。质谱条件Finnigan SurveyorTM HPLC-Finnigan TSQ,ESI源,Xcalibur 1.2数据软件 LCQ数据处理软件,ESI离子源,负离子扫描模式扫描范围m/z 100~800,鞘气流15 arb,辅助气流15 unit,喷雾电压4 000 V,毛细管温度300℃。 结果: 推测了大鼠尿液和胆汁中5个代谢产物的相对分子质量、保留时间、紫外最大吸收波长、二级质谱裂解规律及化学结构。 结论: 在尿液排泄中以硫酸酯化为主要的代谢途径,而在胆汁排泄中以葡萄糖醛酸化为主要的代谢方式。

关 键 词:白藜芦醇  代谢产物  液相色谱-串联质谱  胆汁  尿液

Abstract:Objective: Identified the metabolites of resveratrol in vivo. Method: A method using liquid chromatography-electrospray ionization tandem mass spectrometry (LC-MS-MS) analysis was established for the identification of metabolites of resveratrol. The rat urine and bile samples were pretreated by solid-phase extraction (SPE) method after oral administration at a dose of 100 mg·kg-1 of resveratrol. Result: Five metabolites were identified on their MS fragmentation behaviors by LC-MS-MS method with electrospray ionization (ESI) in negative ion mode. Conclusion: The results indicated the method could be used to rapid screen and identify the conceivable structures of active components responsible for pharmacological effects of resveratrol.
Keywords:resveratrol  metabolites  LC-MS-MS  bile  urine
