Objective Based on "brain-gut axis" theory, the mechanism of Coptidis Rhizoma in treating chronic enteritis, insomnia and depression was analyzed by network pharmacology and molecular docking. Methods The active constituents and related targets of Coptidis Rhizoma were obtained from TCMSP database, and the related targets of chronic enteritis, insomnia and depression were predicted from GeneCards, OMIM and Drugbank databases. The protein interaction network of intersecting targets was built by STRING database, the core targets were predicted by network topological parameters. GO and KEGG analysis were finished by Metascape platform, and the core targets were verified by molecular docking. Results Nine active compounds of Coptidis Rhizoma were obtained, and the main active compounds included quercetin, (R) -canadine, berlambine, palmatine, berberine. There were 38 intersection targets and 19 core targets with chronic enteritis, insomnia and depression, among which IL-6, IL-1β, AKT1, TNF, FOS and other targets had higher degrees. GO and KEGG analysis showed that the core targets played a regulatory role mainly through AGE-RAGE, IL-17, TNF and other signaling pathways, and molecular docking showed the good docking activity. Conclusion Although chronic enteritis, insomnia and depression are different diseases, they are interconnected through the "brain-gut axis". Network pharmacological analysis showed that Coptidis Rhizoma treated chronic enteritis, insomnia and depression through multi-component, multi-target and multi-pathway pharmacological action.
