Abstract: Objective To investigate the pharmacological mechanism of Astragalus-Rhizoma Saposhnikovia divaricata against Covid-19. Methods The effective components and related target protein of Astragalus-Rhizoma and Saposhnikovia divaricata were screened via the Traditional Chinese Medicine Systems Pharmacology (TCMSP) analysis platform. An effective compound- target protein visual network was established using Cytoscape software, and topology analysis was performed. The targets related to COVID-19 were found via the GeneCards online analysis platform. The core targets were selected by the Venny platform, and a protein-protein interaction (PPI) network of the core targets was constructed and analyzed by STRING database. GO (Gene Ontology) enrichment and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment of target protein coding genes were performed using DAVID database. Results A total of thirty-six types of effective compounds which included quercetin, kaempferol and wogonin, 215 targets and 59 core targets which included VEGFA, IL-6, TNF, TP53 and MAPK8 were selected. GO functional enrichment analysis obtained 286 GO items (P<0.05), while KEGG pathway enrichment analysis obtained 97 pathways related to COVID-19 P<0.05), involving cancer signaling pathways, HIF-1 and Toll like signaling pathways. Conclusion The active compounds in Astragalus-Rhizoma Saposhnikovia divaricata drug pair can exert a preventive or therapeutic effect on COVID-19 by means of multiple components, multiple targets and multiple pathways.
