In this study, a network pharmacological screening method was adopted to further study the active ingredients and action mechanism of total flavonoids of Hippophae rhamnoides(TFH) for the treatment of myocardial ischemia. Firstly TCMSP database and PubChem database were searched, and then the data were combined with oral bioavailability and drug analysis to screen flavonoids of H.rhamnoides compounds. Then predictive analysis was conducted for the 7 screened compounds by ChemMapper server.The obtained potential targets were imported into MAS 3.0. Database, and KEGG database was also used for targets analysis and pathway analysis. Finally Cystoscope 3.3.0 software was used to draw "compounds-targets-pathway" network diagram. Virtual experiments predicted 68 potential targets and 60 signaling pathways, and 31 targets and 23 pathways of them were directly or indirectly associated with myocardial ischemia. The results showed that TFH played a synergistic rolemainly through the regulation of calcium signaling pathway, VEGF signaling pathway and gap junction signaling pathway, which was consistent with literature reports. These results indicated that it can enhance heart function, protect vascular endothelial cells, and fight against myocardial ischemia probably by regulating platelet aggregation, lipid metabolism, inflammation and other processes.
