Investigation of the Mechanism of Volatile Oil from Zanthoxylum Armatum DC. in Intervening HyperlipidemiaBased on Network Pharmacology and GC-MS

Objective Based on gas chromatography-mass spectrometry GC-MS combined with network pharmacologymethods this study explored the active ingredients and mechanisms of the volatile oil from Zanthoxylum armatum DC. inintervening hyperlipidemia providing a theoretical basis for the research on functional components in the volatile oil fromZanthoxylum armatum DC. and its intervention mechanism in hyperlipidemia. Methods Initially the chemicalcomponents of the volatile oil from Zanthoxylum armatum DC. were identified by GC-MS and then the correspondingtargets of the chemical components and the disease targets of hyperlipidemia were obtained through databases. The keytargets of the volatile oil from Zanthoxylum armatum DC. in intervening hyperlipidemia were obtained through Venndiagram protein-protein interaction analysis GO analysis KEGG metabolic pathway enrichment analysis and construction of the ?? target-pathway-active ingredient network. Finally the molecular docking software AutoDock wasused to validate the semi-flexible docking of the main active compounds from the volatile oil from Zanthoxylum armatumDC. with the key targets. Results 29 chemical components were identified in the volatile oil from Zanthoxylum armatumDC. obtaining 37 core targets for intervening hyperlipidemia which are involved in cellular responses to lipids lipidlocalization regulation and responses to lipopolysaccharides. Through KEGG enrichment analysis and the ??target-pathwayactive ingredient network 28 key targets including PPARA RXRA TNF NR1H3 PPARG and IL-6 as well as7 main active ingredients such as farnesol linoleic acid and α-caryophyllene were obtained. The molecular dockingresults showed that the key targets had good binding abilities with the main active ingredients with binding energies all lessthan -7. 0 kJ/ mol. Conclusion Various functional components in the volatile oil from Zanthoxylum armatum DC. mayintervene hyperlipidemia by acting on key targets such as PPARA RXRA TNF NR1H3 PPARG and IL-6. This studyexplores the mechanism of the volatile oil from Zanthoxylum armatum DC. in intervening hyperlipidemia aiming to providetheoretical support for further research on the functional components in the volatile oil from Zanthoxylum armatum DC.
