Objective To investigate the molecular mechanism of Qiqilian Formula in treating hypertension. Methods UHPLC-MS/MS was employed to identify the components of Qiqilian Formula. Active components and their corresponding targets were predicted using the SWISS ADME and SWISS Target Prediction databases. Hypertensionrelated genes were obtained from the DisGeNET,DrugBank,GeneCards,OMIM,and TTD databases. Intersecting targets were derived by matching the predicted active component targets with hypertension-related gene targets. These intersecting targets were imported into the STRING database to predict the protein-protein interaction (PPI) network, and the cytoHubba plugin (MCC mode) in Cytoscape 3.9.1 was used to select the top 5 genes as core genes. GO and KEGG pathway enrichment analyses were performed using the Metascape database. Molecular docking was conducted between the core active components and core genes. Results A total of 65 active components and 803 corresponding targets were identified for Qiqilian Formula, along with 1 304 hypertension-related gene targets. The core active components of Qiqilian Formula were magnoflorine, naringenin, quercetin-3-methyl ether, and isorhamnetin. The core targets for treating hypertension included STAT3, PTPN11, and JAK1. Qiqilian Formula appears to regulate hypertension through pathways such as lipid and atherosclerosis, the PI3K/Akt signaling pathway, and the AGERAGE signaling pathway. Molecular docking results indicated favorable binding interactions between the core components and core targets, with binding energies≤-5.0 kcal·mol-1 . Conclusion Qiqilian Formula exerts its preventive and therapeutic effects on hypertension through a multi-component, multi-target, and multi-pathway mechanism.
