Objective: To explore the potential active ingredients and possible mechanisms of Tremella fuciformis in improving constipation. Method: Search for potential active ingredients, targets, and constipation related targets of Tremella fuciformis and Auricularia auricula in databases such as CNKI, Wanfang, CQVIP, TCMSP, PubChem, HERB, and DisGeNET. We import the intersection targets into STRING and Cytoscape 3.10.3 software for analysis, and use Cytohuba plugin to explore the core genes that improve constipation in Tremella fuciformis, perform GO and KEGG enrichment analysis using DAVID database, and perform molecular docking and visualization analysis using Auto Dock Tools-1.5.6 and PyMOL software. Results: The results showed that there were 23 active ingredients in Tremella fuciformis and Auricularia auricula, 402 predicted targets for compounds, 7804 targets for constipation, and 305 intersecting targets between Tremella fuciformis active ingredients and constipation. After topological analysis, 10 core target proteins for constipation improvement were obtained. GO and KEGG enrichment analysis showed involvement in multiple biological processes, cellular components, and molecular functions. The key signaling pathways include AKT1, STAT3, IL6, and TNF. The molecular docking results indicate that the active ingredients have a good binding effect with the target, especially quercetin and baicalein, which have low binding energies with AKT1. This suggests that quercetin and baicalein may improve constipation by regulating the protein kinase B-related signaling pathway. Conclusion: Through network pharmacology analysis and molecular docking, this study identified important active ingredients in addition to Tremella fuciformis polysaccharides, including palmitoleic acid, %K 银耳， %K 便秘， %K 网络药理学， %K 作用机制， %K 分子对接
