Methods: The principal chemical components of fuzi were obtained through TCMSP, ETCM, HERB, and SymMap databases, and the active ingredients were screened according to ADME;the corresponding targets of the components were searched on STP database and the important targets of diseases were obtained through the Gencards and OMIM databases. The intersection of compound target and disease target was obtained and the coincidence target was imported into STRING database to construct a PPI network. The DAVID database platform was used to analyze “drug-ingredient-target” and the biological processes and pathways involved, and finally the molecular docking verification was carried out through AutoDock Vina. Results: The core active ingredients of Fuzi bring back yang and rescue from the collapse are deltoin, karakoline, (R)-norcoclaurine. The protein with a higher degree in the PPI network is EGFR, MAPK1, MAPK3. Molecular docking verification also shows the binding activity between the target and the ingredients better. The signaling pathways mainly include cAMP, MAPK and PI3K-Akt signaling pathway. Conclusion: This study reveals a comprehensive explanation of the traditional efficacy of fuzi huiyangjiuni, and provides a reference for subsequent basic research.展开更多
