摘要

Dengzhan Shengmai Capsule (DZSMC) is a traditional Chinese medicine (TCM) formula with remarkable clinical effect in the treatment of stroke sequelae. Exploring the components of DZSMC and detecting the absorbed prototype constituents and metabolites in blood are of great significance to clarify the effective substances of this prescription. Here, a reliable method using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS) was established for the comprehensive analysis of chemical constituents of DZSMC and their metabolites in rat plasma after gastric perfusion. Two acquisition modes, including MSE mode and Fast DDA mode, were performed for acquiring more precursor ions and cleaner precursor-product ions background during the study of constituents of DZSMC. As a result, a total of 125 constituents were unambiguously characterized or tentatively identified. For the first time, a total of 92 components, including 44 prototype components and 48 metabolites were unambiguously or tentatively identified in rat plasma. The metabolic pathways included phase I reactions (hydration, hydrogenation, oxidation, demethylation and hydroxylation) and phase II reactions (conjugation with glucuronide, sulfate and methyl). Furthermore, the metabolites from caffeic acid and scutellarin were characterized and validated by phase II metabolic reactions in vitro, which could be established as a simulated in vivo environment of metabolites identification and verification of TCM formula. It is the first systematic study on metabolism of DZSMC in vivo and could also provide a valid analytical strategy for characterization of the chemical compounds and metabolites of TCM formula.
