摘 要:目的:建立靶细胞萃取联用UPLC/Q-TOF-MS技术分析川芎中药效成分的方法。方法:选用人脐静脉内皮细胞(HUVEC)作为靶细胞,萃取川芎中的药效成分。在细胞对数生长期加入川芎供试品溶液,孵育2 h收集细胞并用液氮迅速冷冻,反复冻融使细胞破碎,离心得到萃取药物后的细胞样品。采用UPLC/Q-TOF-MS对其进行检测,分析川芎化学成分中与细胞结合的物质,即川芎中与细胞结合进一步发挥药效的可能有效成分。结果:从川芎中筛选到2个可能的药效成分,分别为阿魏酸和藁本内酯。结论:本研究建立的方法可以通过化合物与细胞中靶点(受体、通道、酶等)之间的特异性结合作用,筛选出川芎中药效活性成分,从而为药物活性成分的筛选以及药物机制的研究提供思路,同时推动了中药安全性的快速发展。Objective: To establish a method by using target cell and UPLC/Q-TOF-MS for extraction the pharmacodynamic components in Chuanxiong Rhizoma. Methods: The human umbilical vein endothelial cells (HUVEC) were used as target cells, and the freeze-dried powder of Chuanxiong Rhizoma in logarithmic growth period was added. After 2 h incubation, the cells were collected and frozen rapidly with liquid nitrogen, the cells were broken by repeated freezing and thawing, and cen- trifuged to obtain a sample of cells after extraction. While compounds in the extract of cell samples were determined by UPLC/Q- TOF-MS, the effect of possible effective components that entered the cell of Chuanxiong Rhizoma was analyzed. Results: After HUVEC extraction two active ingredients ferulic acid and ligustilide were obtained. At the same time, the method was estab- lished for the determination of the two components. Conclusion : The analysis method of the target cell extraction and UPLC/Q- TOF-MS can be applied for screening out the active ingredients in Chuanxiong Rhizoma by specific binding effect between the compound and the target (receptor, channel, enzyme, etc. ) in the cell, so as to provide a new method for screening the ac- tive ingredients and drug mechanism study.
