Traditional Chinese MedicineSystems Pharmacology Database and Analysis Platform (TCMSP) was used to obtain the active components of Glycyrrhizae Radix et Rhizoma-Granati Pericarpium formula and their corresponding targets. The obtained targets were input to the UniProt database to inquire the genenames corresponding to the targets. By searching the CTD database,Genecards database and OMIM database of disease-related websites,the anti-sunburn targets were obtained. The interaction of the active targets was analyzed with online STRING database to screen the predicted core targets. The gene ontolog(GO) gene function enrichment analysis and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis of the predictive targets were performed by using DAVID database. Cytoscape 3.6.1 software was used to make "drug-component-target" network diagram,"protein-protein interaction" network diagram and "component-target-pathway" network diagram. Online website Draw Venn Diagram was used to show the relationship between disease targets and drug predicted targets. R Studio software was used to draw the functional enrichment analysis diagram of GO gene and KEGG pathway. Molecular docking between the active ingredients and the core targets was performed using GOLDsoftware.
Based on the method of network pharmacology,the present study has preliminarily explored the anti-sunburn targets and pathways of Glycyrrhizae Radix et Rhizoma-Granati Pericarpium formula,and further verified the characteristics of multi-component and multi-target treatment of diseases in TCM,so as to provide certain scientific ideas for the modernizationresearch of Chineseherbal compound prescriptions.
