[Objectives]To explore the pharmacodynamic material basis of Sijicao granules for the treatment of eczema through chemical composition-network pharmacology.[Methods]First of all,the chemical constituents of Polygonum capitatum and plantago asiatica from Sijicao granules were collected,and the relevant target information of the constituents was collected by TCMSP,PubChem,DisGeNET,GeneCards and STRING ***,Cytoscape 3.8.2 software was used to construct the chemical compounds-target network map of Sijicao ***,STRING database was used for PPI protein network analysis,GO functional enrichment analysis and KEGG pathway enrichment analysis of core targets,and molecular docking between core constituents and protein targets was also performed.[Results]30 constituents,including quercetin,kaempferol,luteolin,ellagic acid and gallic acid,were discovered to be the key effective compounds of Sijicao granules in the treatment of *** its core action protein targets were PTGS2,NOS2,AKT1,TP53,IL6,*** s more,through GO functional enrichment analysis of biological process(BP),cell component(CC),molecular function(MF)analysis and KEGG pathway enrichment analysis,the main pathways of action of Sijicao granules for the treatment of eczema including IL-17 signaling pathway,T cell receptor signaling pathway,cancer signaling pathway,TNF signaling pathway and Relaxin signaling *** addition,molecular docking results displayed that the primary active constituents quercetin,kaempferol and luteolin were well combined with the core protein targets AKT1 and IL6.[Conclusions]Sijicao granules could play an important role for the treatment of eczema through multi-component,multi-target,multi-pathway and their interaction.
