Objective To Analyze the chemical composition of Xiaoer Foshao Hezhong Granules (XFHG) by HPLC-Q-TOF-MS/ MS, then predicting the pharmacodynamic substance basis of treating functional abdominal pain based on its chemical composition and network pharmacology, checking out the potential efficacy ingredients and mechanism of action.Methods HPLC-Q-TOF-MS/ MS was used to analyze the chemical composition of XFHG, which were scanned in positive and negative modes respectively. The chemical composition was confirmed by matching the reference substance with the fragment ion information and retention time in the Systems Pharmacology Database and Analysis Platform of traditional Chinese medicine (TCMSP) and literatures. The chemical components obtained through mass spectrometry analysis with oral bioavailability ≥ 20% and drug like properties ≥ 0.5 were selected, and the target components specified in the 2020 edition of the Chinese Pharmacopoeia and the components screened from the SwissADME database were included as active ingredients. By using TCMSP, Massbank, Herbal Pharmacopoeia Database, Genecards Database, and literature screening, we established target databases for active ingredients of XFHG, as well as target databases for functional abdominal pain related diseases. We screened common targets and imported them into the network visualization software Cytoscape 3.9.1 to construct a target interaction network diagram for "XFHG-components-functional abdominal pain", and screened the core components. Import common targets into the STRING 11.5 database, construct a protein protein interaction (PPI) network diagram, and import the obtained data into Cytoscape 3.9.1 to screen out the core targets. The core targets were imported into the DAVID database for Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and Gene Ontology (GO) enrichment analysis.Results There were 96 chemical components analyzed by qualitative analysis of XFHG, including 26 flavonoids, 17 organic acids, 13 terpenoids, 11 alkaloids, 6 lemon, 8 phenylpropanoids, 4 benzylethanol side and 11 other classes. Screening out 15 core components that play a therapeutic role in functional abdominal pain, sourced from six medicinal herbs, including berberine, paeoniflorin, forsythrin A, forsythrin, evodiamine, rutaecarpine, etc. The core targets of XFHG for treating functional abdominal pain include TNF, AKT1, IL6, IL-1β, VEGFA, TP53, CASP3, PTGS2, CAT, and MAPK3. A total of 109 pathways were identified through KEGG pathway analysis, with immune response and inflammatory response related signaling pathways ranking high. GO enrichment analysis yielded 145 entries for biological processes (BP), 10 entries for cellular components (CC), and nine entries for molecular functions (MF). The entries with the highest enrichment values involved biological processes related to inflammation, such as lipopolysaccharide-mediated signaling pathways, glucocorticoid responses, and positive regulation of nitric oxide biosynthesis processes.Conclusion Based on the chemical components analyzed by HPLC-Q-TOF-MS/ MS combined with network pharmacology, the potential efficacy components of XFHG in the treatment of functional abdominal pain were predicted, and its mechanism of action was predicted to be related to immune regulation and anti-inflammatory effects.
