{Abstract}: Ovarian cancer (OC) is a common malignancies of the female genitalia. P. montana var. lobata (Willd.), a herb with anti-tumor effects, is widely used in the clinical treatment of ovarian cancer (OC), but the ingredients and molecular mechanism of action remains to be explored. In this study, we extracted the main active ingredients of P. montana var. lobata (Willd.) from the TCMSP database, and predicted its potential targets of action against OC from the DisGeNET and GeneCards databases. Protein-protein interaction (PPI) was constructed using the STRING database, while pathway enrichment analyses were performed using the DAVID database. Next, we generated an Ingredient-Target-Pathway network using Cytoscape 3.7.2, then processed the key targets of action and main active ingredients for molecular docking. The results showed that seven active ingredients of P montana var. lobata (Willd.) were associated with treating for OC, namely beta-sitosterol, coumestrol, daidzein, formononetin, genistein, puerarin and scoparone, two important targets Casp3 and Jun, and signaling pathways of P. montana var. lobata (Willd.) against the progression of OC. TUNEL staining, enzyme-linked immunosorbent assay (ELISA), and Western blot assays, the pharmacodynamic effect of puerarin in the treatment of OC and the major targets were verified. Animal experiment demonstrated that application of puerarin at different times of modeling not only upregulated expression of Casp3, Smac, and c-jun proteins, but also promoted apoptosis in tumor cells, hence inhibiting progression of OC. This study demonstrates that P. montana var. lobata (Willd.) can thereby induce apoptosis in tumor cells and inhibit malignant progression through activating expression of Casp3, smac, and c-jun proteins to regulate related apoptosis pathways, as validated by network pharmacology predictions and animal experiments, and can be verifed by large-scale clinical trials in the future. This study also provides theoretical support and new research perspectives for this disease.
