Abstract:

The study aims to explore the root components of Hylocereus undatus and its potential antioxidant mechanism. Based on liquid chromatography-tandem mass spectrometry (LC-MS/MS), the components of Hylocereus undatus root were identified, and the active components of Hylocereus undatus root were analyzed by TCMSP database. Based on the in vitro efficacy evaluation test, the potential efficacy of the ethanol extract of Hylocereus undatus root was preliminarily screened. Based on Swiss Target prediction, the potential efficacy targets of active ingredients in Hylocereus undatus root were screened. The protein-protein interaction (PPI)network was constructed by Cytoscape and String screening. Metascape database and Cytoscape 3.9.1 software were used for GO and KEGG enrichment analysis, and the active ingredient-potential efficacy target-symptom map of Hylocereus undatus root was constructed. The molecular docking was carried out with Auto Dock software. The results show that 1 041 substances in the root of Hylocereus undatus are identified, and it is found that the substances related to antioxidant efficacy in the root of Hylocereus undatus are abundant, reaching 25.84%. The DPPH·, ABTS·+ and OH· scavenging efficiency of the ethanol extract of pitaya root is equivalent to that of 0.1% Vc. Cytoscape analysis shows that 18 active components such as galangin, kaempferol and quercetin in Hylocereus undatus roots can participate in the antioxidant process. There are 30 potential core targets involved in the antioxidant process. KEGG is enriched into 4 antioxidant-related pathways, involving ErbB signaling pathway, PI3K-Akt signaling pathway, TNF signaling pathway, and Foxo signaling pathway. Molecular docking shows that 18 active components of Hylocereus undatus root have good binding activity with EGFR and ATK1, and some active components have good activity with TNF.
