Objective To explore the active components and the anti-cancer mechanism of Zingiberis Rhizoma by network pharmacology. Methods The components of Zingiberis Rhizoma were searched through the Chinese Medicine System Pharmacology (TCMSP) database. The active components of Zingiberis Rhizoma were screened with "Lipinski rule" and "Oral Bioavailability ≥ 30%" rules, the corresponding targets of the active components were predicted. Cytoscape 3.2.1 was used to build a network between components and targets. Anti-cancer targets were searched from Genecards database with the keyword "anticancer", the anti-cancer targets was mapped to the targets of Zingiberis Rhizoma to screen out the common targets as the anti-cancer targets of Zingiberis Rhizoma. The anti-cancer targets of Zingiberis Rhizoma were imported into STRING database for proteinprotein interaction analysis, and the target protein interaction network graph (PPI) was constructed. Cytoscape 3.2.1 "CytoNCA" plug-in unit was used to screen the key anti-cancer targets of Zingiberis Rhizoma. DAVID database and Cytoscape 3.2.1 "ClueGO" plug-in unit were used to perform KEGG pathway enrichment analysis and GO biological process enrichment analysis, and build active ingredients-key anticancer targets-KEGG pathway network map. Results 52 components and 101 corresponding targets of Zingiberis Rhizoma with drug-like properties and good oral absorption were obtained. Among them, there were 39 targets with anticancer effects and 10 key anti-cancer targets. KEGG signaling pathway analysis of anti-cancer targets of Zingiberis Rhizoma obtained 68 signaling pathways, mainly related to TNF signaling pathway and VEGF signaling pathway, etc. GO biological process analysis obtained 35 biological processes, mainly involved in nitric oxide biosynthesis, cell proliferation and apoptosis, etc. Conclusion This study preliminarily revealed the pharmacodynamic substance basis of Zingiberis Rhizoma and its possible anticancer pharmacological effects, providing basis for anti-cancer research of Zingiberis Rhizoma.
