Abstract: This study employed ultrahigh-performance liquid chromatograph-hybrid quadrupole orbitrap high resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS) to detect the chemical constituents of traditional Chinese medicine in Sizi Dingchuan granules. Network pharmacology and molecular docking techniques were then utilized to predict the effects of Sizi Dingchuan granules on bronchial asthma, along with its target molecules and signaling pathways. UHPLC analysis identified 172 compounds, including 84 flavonoids, 38 organic acids and their derivatives, 22 phenylpropanoids, 16 organic oxygen compounds, 3 phenolic compounds, 2 terpenoids, 2 sugars and glycosides, and 5 other compounds. Typical compound fragmentation patterns were documented. Using network pharmacology methods, 117 compounds were ultimately selected for target prediction, establishing a “drug-component-target-disease” network, which revealed that quercetin, schisandrin A, baicalin, gomisin H, and baicalin exhibit multiple targets related to bronchial asthma, suggesting that they may be the active components responsible for the compound’s efficacy in treating this condition. Protein-protein interaction analysis identified core targets including TNF, IL-6, JAK2, STAT3, BCL2, CASP3, and EGFR, primarily clustered within the JAK-STAT signaling pathway. This suggests that the main components of Sizi Dingchuan granules may regulate the balance between Th17 and Treg cells, as well as Th1 and Th2 cell differentiation, by modulating the JAK-STAT signaling pathway, thereby exerting a positive therapeutic effect on bronchial asthma.
