Objective To explore the material basis and mechanism of Dracocephalum moldavica L. in the prevention and treatment of dementia.Methods The active compounds contained in D. moldavica were screened by literature mining and pharmacokinetic parameters, and the targets related to dementia were collected by searching drugbank, genecards and OMIM databases. Cytoscape software was used to construct the protein interaction network of D. moldavica for the prevention and treatment of dementia. Gene ontology and signal pathway enrichment were analyzed. The key target pathway network of D. moldavica compounds was constructed. Results 42 active components were screened, 90 potential drug targets for the prevention and treatment of dementia were obtained, 74 main targets were further screened in the protein-protein interaction network, and 300 signal pathways, 1 465 biological processes, 104 cell components and 108 molecular functions were enriched. Through the compound-target-pathway network, the key compounds that play a role in the prevention and treatment of dementia, such as acacetin, apigenin, chrysoeriol and other flavonoids, as well as the corresponding key targets and key signal pathways, such as MAPK, APP, MAPT, PI3K and Alzheimer's disease, neurotrophic protein and other pathways were obtained. Conclusion D. moldavica has the characteristics of multi-component, multi-target and multi-channel in the prevention and treatment of dementia.
