整合HPLC-Q-TOF-MS与网络药理学阐明八珍袋泡茶防治气血两虚证的潜在作用机制研究OA

Objective To identify the chemical constituents of Bazhen tea bag by high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(HPLC-Q-TOF-MS)and,in combination with network pharmacology,to investigate the potential mechanism of Bazhen tea bag in the prevention and treatment of qi and blood deficiency pattern.Methods The chemical constituents of Bazhen tea bag were systematically identified by HPLC-Q-TOF-MS.Based on oral bioavailability and Lipinski's rule of five,the potential active constituents of Bazhen tea bag were screened.Targets and disease-related information were collected through online target prediction platforms,a protein-protein interaction(PPI)network for hub targets was constructed,and enrichment analysis was performed.Enrichment analysis was performed using the DAVID Bioinformatics Resources database to identify major biological pathways associated with key targets.Cytoscape 3.7.1 was used to construct a"drug-constituent-target"interaction network of Bazhen tea bag,and the mechanism of Bazhen tea bag in the prevention and treatment of qi and blood deficiency pattern was further analyzed.Results A total of 72 chemical constituents were identified,and on this basis,50 core targets related to the prevention and treatment of qi and blood deficiency pattern were screened.The PPI network analysis showed that target proteins such as tumor protein p53(TP53),epidermal growth factor receptor(EGFR),protein kinase B1(AKT1),HSP90AA1,and CTNNB1 were closely connected,in the network topology,to signaling pathways related to qi and blood deficiency pattern.Network pharmacology results further revealed that representative active constituents in Bazhen tea bag,such as ferulic acid,coniferin ferulate,atractylenolide II,3β-hydroxyatractylone,ellagic acid,liquiritin,and ligustilide,have potential for binding to key sites of proteins related to the regulation of qi and blood deficiency pattern.Conclusion The material basis of Bazhen tea bag was preliminarily identified,and it was clarified that this formula may exert preventive and therapeutic effects on qi and blood deficiency pattern through regulation of signaling pathways such as MAPK,JAK-STAT,and PI3K-Akt.
