Objective To study the prototype components and metabolites in rat liver tissue after ig administration of Shaoyao Gancao Decoction and its metabolic pathways in vivo. Methods The liver tissue samples of SD rats were collected at 11 different time points after ig administration of the water decoction extract of Shaoyao Gancao Decoction (0.4 g∙kg⁻¹). An ultra-high performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF-MS/MS) technique was used to detect the drug-containing liver tissue samples at different time points. Analyst ® TF 1.7.1 Software was used to preliminarily process the mass spectrometry data, and then PeakView 2.0 and Masterview 1.0 were used for advanced analysis and visualization to obtain the retention time and mass spectrometry information of prototype components and metabolites. Combined with the metabolite analysis and recognition function of MetabolitePilotTM1.5 Software, the prototype components and metabolites in drug-containing serum samples at different time points were analyzed, and the metabolic rules in vivo were summarized. Results In the negative ion mode, a total of 71 prototype components were detected from rat liver tissue, including 35 flavonoids, 19 terpenoids, 9 volatile oils, 5 coumarins, 2 organic acids and 1 other component (protocatechuic aldehyde). At the same time, 540 metabolites were detected. It is speculated that the metabolic pathways of the main chemical components of Shaoyao Gancao Decoction in liver tissue mainly include glycosidic bond hydrolysis, ester hydrolysis, dealkylation, oxidation, reduction, demethylation, methylation, glucuronidation, sulfation, and glycine. Conclusion The prototype components and metabolites of Shaoyao Gancao Decoction in rat liver tissue were preliminarily determined, it provided a reference for further explaining the pharmacodynamic material basis and mechanism of Shaoyao Gancao Decoction.
