Objective To study the constituents and metabolites in rat brain after ig administration of Xueshuan Xinmaining Tablet (XXT) based on the serum medicinal chemistry. Methods The acute blood stasis rat model was replicated by ice bath-adrenalin method, and XXT[1.4 (g·kg-1·d-1)] was administered orally for 8 d. The brain samples were collected and pretreated after ig administration for the last time. Then the absorbed prototype constituents and their metabolites in rats plasma were rapidly analyzed and identified by combination of ultra-high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF/MS) and multivariate statistical analysis. Results Finally, a total of 11 absorbed prototype constituents and three metabolites were identified, including phenanthrene, bufonis venenum oxadiene, and other structural types of compounds. These constituents absorbed into brain may be the potential bioactive components in XXT. Conclusion The establishment of UPLC-Q-TOF/MS analysis method explained comprehensively the brain migration component of XXT, and provided scientific basis for clarifying its substance basis of pharmacodynamics of this large variety of Chinese medicine.
