Objective To study the components, targets, and mechanism of Rubi Fructus in treatment of postmenopausal osteoporosis by network pharmacology and molecular docking. Methods Active components, component targets, and disease targets of Rubi Fructus were collected by using TCMSP, GeneCards, OMIM, TTD, and DisGeNET databases and seeking the literature data. The drug active components-target network and the interaction network of postmenopausal osteoporosis targets were constructed using String database and Cytoscape software. The enrichment analysis of GO and KEGG pathways was performed using the CludterProfiler package in R Studio software. Finally, the prediction results were verified by molecular docking. Results A total of 16 active components of Rubi Fructus were screened, including β-sitosterol, ursolic acid, rubusin A, sitosterol, rubusin B, ellagic acid, and oleanolic acid, which were the core components of Rubi Fructus in treatment of postmenopausal osteoporosis. Core targets such as ALB, SRC, CASP3, MMP-9, ESR1, HRAS, PPARG, MAPK1, and MAPK14 were screened. Several GO functions and KEGG pathways were enriched, such as chemical carcinogenic-receptor activation, PI3K-Akt signaling pathway, lipids and atherosclerosis, MAPK signaling pathway, proteoglycan in cancer, etc., and the molecular docking results were good. Conclusion Rubi Fructus can treat postmenopausal osteoporosis through multiple components, multiple targets and multiple signaling pathways.
