| 摘要: |
| 目的 进行小檗碱和药根碱在大鼠肝微粒体中的代谢转化研究，尝试给中药有效成分的体外和体内关联研究提供一定的参考。方法 制备大鼠肝微粒体，用Brad ford法测定酶活性，以此配制大鼠肝微粒体体外温孵体系，加入药物温孵，用质谱进行检测测定并比较小檗碱、药根碱代谢产物图谱。结果 检测到小檗碱经大鼠肝微粒体代谢后产物中有药根碱，药根碱经大鼠肝微粒体代谢后产物中有巴马汀，但小檗碱代谢产物中未见巴马汀。结论 小檗碱和药根碱是同母核生物碱，在肝微粒体中孵化可相互影响，但体外代谢无法简单关联体内代谢过程。 |

| Abstract: |
| Objective To investigate the metabolic transformation of berberine and jatrorrhizine in rat liver microsomes, and to provide a reference for the in vitro and in vivo association studies of active constituents in traditional Chinese medicine (TCM). Methods The rat liver microsome was prepared, and the enzymatic activity was determined by Brad ford method to prepare the in vitro incubation system of rat liver microsomes. After the incubation in the presence of berberine and jatrorrhizine, mass spectrometry was used to detect and compare the metabolites of berberine and jatrorrhizine. Results After the metabolic transformation in rat liver microsomes, jatrorrhizine was one of the metabolites of berberine; palmatine was one of the metabolites of jatrorrhizine, but not of berberine. Conclusion Berberine and jatrorrhizine are from the same parent alkaloid and they can affect each other during the incubation in liver microsomes. However, the in vitro metabolism cannot be associated with the in vivo metabolism. |
