ABSTRACT
Objective To investigate the effect of compatibility on brain tissue distribution in rat of corydaline, tetrahydropalmatine, protopine, imperatorin and isoimperatorin in Corydalis Rhizoma and Angelicae Dahuricae Radix, and to provide further experimental evidence for confirming the Q-marker of Yuanhu Zhitong Prescription. Methods After oral administration of Corydalis Rhizoma, Angelicae Dahuricae Radix, and Yuanhu Zhitong Prescription extracts respectively, the concentration of five compounds in brain tissue samples at different time points was determined by UPLC-MS/MS, and the effect of compatibility on brain tissue distribution was further evaluated by kinetic parameters. Results Compared with single-herb group, AUC and Cmax of corydaline, tetrahydropalmatine and protopine in Yuanhu Zhitong Prescription group were increased significantly, and MRT of imperatorin and isoimperatorin were prolonged at the same time. Conclusion Corydalis Rhizoma and Angelicae Dahuricae Radix exist synergistic effect, the compatibility of these two herbs promote brain tissue distribution of corydaline, tetrahydropalmatine, protopine, imperatorin and isoimperatorin, which can be used as Q-marker of Yuanhu Zhitong Prescription.
