Abstract: 【Objective】 The purpose of this experiment was to explore the pharmacological activity and overall mechanism of compound plant essential oils (oregano essential oil,cinnamaldehyde,Eucalyptus oil) based on network pharmacology.【Method】 The targets of compound plant essential oils were screened using TCMSP database.The drug-ingredient-target network was constructed by Cytoscape 3.7.1 software,and PPI network was constructed by STRING and visualization.The targets were annotated by GO function and KEGG pathway enrichment analysis through DAVID database.And AutoDock Vina software was used for molecular docking of selected active components and key targets.【Result】 Compound plant essential oils acted on the key targets including interleukin 6 (IL6),prostaglandin-endoperoxide synthase 2 (PTGS2),Toll-like receptors 4 (TLR4),transcription factor p65 (RELA),nitric-oxide synthase,endothelial (NOS3),aryl hydrocarbon receptor (AHR),cytochrome P450 1A1 (CYP1A1),NF-kappa-B inhibitor alpha (NFKBIA),gamma-aminobutyric-acid receptor alpha-2 subunit (GABRA2) and so on with 8 active ingredients.The GO function enrichment analysis showed that 269 items were obtained,181 items were related to biological processes,involving adenylate cyclase-activating adrenergic receptor signaling pathway,regulation of postsynaptic membrane potential,etc.,59 items related to cell components,involving integral component of plasma membrane,neuron projection,etc..29 items related to molecular functions,involving neurotransmitter receptor activity,excitatory extracellular ligand-gated ion channel activity,etc..KEGG pathway analysis showed that 72 items related to signal pathways,and participated in the regulation of neuroactive ligand-receptor interaction,lipid and atherosclerosis,cGMP-PK signaling pathway,calcium signaling pathway,TLR signaling pathway,Th17 cell differentiation,etc..It was also associated with alcoholic liver disease,Kaposi sarcoma-associated Herpesvirus infection and other diseases.The results of molecular docking showed that the core components such as eugenol,caryophyllene,thymol were closely bound to the key targets such as IL6 and PTGS2,and had good affinity.【Conclusion】 The compound plant essential oils might act on key targets such as eugenol,caryophyllene,thymol,D-limonene,cinnamaldehyde and other active ingredients,played an important role mainly through regulating of nerves and immune systems,anti-bacterial,anti-inflammatory and anti-tumor signaling pathways acting on IL6,PTGS2,TLR4,RELA and other key targets.The compound plant essential oils had a multi-component,multi-target,multi-pathway action mechanism.
