Objective By using the method of network pharmacology, to screen the target of "Flos Carthami-Semen Persicae" on prevention and treatment of coronary heart disease (CHD), and to reveal the TCM compatibility mechanism of "Flos Carthami-Semen Persicae" in prevention and treatment of CHD. Methods All chemical constituents of "Flos Carthami-Semen Persicae" were searched by consulting literatures (PubMed, CNKI) and pharmacology database of traditional Chinese medicine (TCMSP). The criteria were ADME parameters (OB ≥ 30% and DL ≥ 0.15) and pharmacodynamic activities. The active compound of "Flos Carthami-Semen Persicae" was screened. Then BATMAN-TCM database was used to screen the targets of active compounds, and the complex network of "active compounds-targets-diseases" was constructed by using Cytoscape 3.6.1 software. STRING database and biological information annotated database (DAVID) were used to analyze the protein-protein interaction. The functional enrichment analysis of gene ontology (GO) and the (KEGG) pathway enrichment analysis based on Kyoto gene and genome encyclopedia were used to study the compatibility mechanism of prevention and treatment of coronary heart disease. Results A total of 255 compounds were retrieved, of which 38 were active compounds, and 718 targets were identified, and 10 potential targets and compatibility mechanism of drugs for prevention and treatment of coronary heart disease were screened out by network topology evaluation, and the mechanism of compatibility of drugs for prevention and treatment of coronary heart disease (CHD) was the most closely related. DAVID database was used to analyze the functional enrichment of GO and the enrichment of KEGG pathway in 10 potential targets. 66 biological processes and 18 signaling pathways involved in the prevention and treatment of CHD were screened out by using "Flos Carthami-Semen Persicae". The most important signaling pathways, such as tumor necrosis factor signaling pathway, malaria signaling pathway, African trypanosomiasis signaling pathway, NOD-like receptor signaling pathway, and so on, were closely related to "Flos Carthami-Semen Persicae" drug in the prevention and treatment of coronary heart disease. At the same time, the biological processes involved include the signal pathway mediated by lipopolysaccharide (LPS), the positive regulation of sequence specific DNA binding transcription factor activity, the positive regulation of protein phosphorylation, the signal transduction of protein kinase B, and the biological activity of nitric oxide (no). The positive regulation of synthesis process and so on; the mechanism of its prevention and treatment of coronary heart disease was mainly through up-regulation or down-regulation of these biological processes and signaling pathways, giving play to multi-component, multi-target and multi-way synergistic biological effects. Conclusion Network pharmacology provides a new idea and method for revealing the TCM compatibility mechanism of "Flos Carthami-Semen Persicae" for the prevention and treatment of coronary heart disease, and also provides a modern scientific connotation for the in-depth research and development of "Flos Carthami - Semen Persicae" drug pair.
