Objective To predict the potential target and mechanism of Notoginseng Radix in treatment of lumbar disc herniation by network pharmacology and molecular docking technique. Methods The active components and targets of Notoginseng Radix were screened from TCMSP database, and "active component-target" network of Notoginseng Radix was constructed. The targets related to lumbar disc herniation were retrieved from GeneCards and OMIM databases, and the intersection targets of drugs and diseases were selected. Protein interaction network (PPI) was constructed using String database, the "component-target-disease" network map was constructed by Cytoscape 3.8.2 software, and GO enrichment analysis and KEGG signaling pathway enrichment analysis were performed by R software. MOE software was used to verify the molecular docking between active ingredients and potential targets. Results A total of 8 active components and 33 effective drug targets of Notoginseng Radix were screened for the treatment of lumbar disc herniation. Among them, prostaglandin endoperoxidase synthase, cysteine proteinase-3, matrix metalloproteinase 9, cell chemokine 2, and other target genes may play key roles. Forty-three items were selected for GO enrichment analysis, which mainly included biological processes such as reaction to lipopolysaccharide and reaction to bacteria derived molecules. Membrane raft, membrane microarea and other cell components. Internal peptidase activity, cytokine receptor binding and other molecular functions. KEGG pathway enrichment analysis obtained 102 items related to inflammation, apoptosis, metabolism, immunity and tumor, among which IL-17 signaling pathway played a key role. The molecular docking results showed that the main active components of Notoginseng Radix had strong binding ability to the core target. Conclusion Notoginseng Radix can play a role in treating lumbar disc herniation through multiple ways and multiple targets.
