Abstract：Objective：To predictthe mechanismof the Sophoradavidi flower extract（SDFE）in preventing and treating pulmonary nodules based on network pharmacology.Methods：The SwissTarget Predictionand GeneCards databases wereusedtoobtainthetarget genes ofcompounds in SDFEandthe therapeutic targetsfor pulmonarynodules，respectively， follwed byidentifying their intersection targets.The STRINGonline platform was employed toconstructaprotein-protein interaction （PPI） networkof theintersectiontargets.GOand KEGG enrichmentanalyses were performedontheintersection targetsusing theDAVID database.Acompound-intersection target-KEGG networkwas constructed using Cytoscape software，and molecular docking validation was conducted using Discovery Studio software.Results：92 intersection targetswere determined.GO functional enrichment analysis revealed thatthese targetswere primarily associatedwith transmembrane receptor protein tyrosine kinaseactivity，positive regulationof kinaseactivity，andreceptorcomplexes. KEGG enrichment analysis indicated significant involvement in pathways in cancer and PI3K-Akt signaling pathway.The commoncore targets inboth thePPI networkandthecompound-intersectiontarget-KEGG network were EGFR，MMP9， SRC and AKT1.The top10core compounds were palmatine，medicarpin，genkwanin，pinocembrin，7-methoxyluteolin， nepetalactone，naringenin，diosmetin，luteolinand matrine.Moleculardocking results showedthatluteolinandmatrine hadLibDockScores greater than10O whenbinding to core targets such as EGFR，MMP9 and SRC.Conclusion：SDFE canprevent and treatpulmonary nodules through multiplecomponents，multiple targets and multiplepathways，providing a theoretical basis for subsequent experimental validation and drug development.
