[Abstract]
Objective To establish a method that using target cell to extract the pharmacodynamic components and quantitative analysis in Corydalis Rhizoma. Methods Take the human umbilical vein endothelial cells (HUVEC) as target cells, and add the freeze-dried powder of yanhusuo in logarithmic growth period. After 2 h incubation, the cells were collected and liquid nitrogen was used to cleave those cell samples. While compounds in the extract of cell samples were determined by UPLC/Q-TOF-MS, the effect of effective components that entered the cell of Corydalis Rhizoma was ananlyzed. Finally, HPLC was used to quantitatively analyze the effective components. Results After HUVEC extraction, five active ingredients were obtained, such as tetrahydropalmatine, berberine, tetrahydroberberine, berberine hydrochloride, and dehydrocorydalinecorydaline, respectively. At the same time, the method was established for the determination of the five components. Conclusion The analysis method of the target cell extraction can reflect the active substance in the medicine, through the interaction between the compound and the cell. This method will play an important role in the study of complex system of traditional Chinese medicine.
