Study on the mechanism of Euphorbia fischeriana Steud.- Jujubae Fructus in the treatment of hepatocirrhosis based on network pharmacology

The active components,targets,and pathways of Euphorbia fischeriana Steud.-Jujubae Fructus in treating hepatocirrhosis and the mechanism of action were explored by means of network pharmacology.Firstly,the active components and related targets of Jujubae Fructus were screened by TCMSP database and standardized by Uniprot database.The compounds of Euphorbia fischeriana Steud.were obtained by searching the literature and finally screened by PubChem database,Swiss ADME,and SwissTargetPrediction.Hepatocirrhosis targets were obtained through Genecards database,PPI network analysis was conducted on common targets of Euphorbia fischeriana Steud.-Jujubae Fructus and hepatocirrhosis by using String database,GO enrichment analysis and KEGG pathway enrichment analysis was conducted through Metascape database by using intersection targets of Euphorbia fischeriana Steud.-Jujubae Fructus and hepatocirrhosis,and the results were drawn by using Weishengxin online drawing platform.Then,the network of drug-compound-target-pathway was constructed by the software of Cytoscape3.8.0.Finally,the above results were verified by molecular docking.47 active compounds from Euphorbia fischeriana Steud.-Jujubae Fructus were screened out,which had 38 common targets,162 intersection targets,and 340 signal pathways with hepatocirrhosis,mainly involving hepatitis C,JAK-STAT signal pathway and AGE-RAGE signal pathway.Targets,such as MAPK1,AKT1,TNF,JUN,IL6 and PTGS2,play important roles in the treatment.The findings suggested that the main active ingredients of Euphorbia fischeriana Steud.-Jujubae Fructus in treating hepatocirrhosis are quercetin,scopolamine,physcion,7-deoxyrangduin,17-Hydroxyjolkinolide A,etc.Molecular docking results showed that the main active components and core targets might have a good binding capacity.This study preliminarily explored the potential mechanism of Euphorbia fischeriana Steud.-Jujubae Fructus in treating hepatocirrhosis and provided a theoretical basis for the clinical application of Euphorbia fischeriana Steud.-Jujubae Fructus.

Comprehensive Metabolic Profiling of Modified Gegen Qinlian Decoction by Ultra-high-Performance Liquid Chromatography-Diode Array Detection-Q-Exactive-Orbitrap-Electrospray Ionization-Mass Spectrometry/Mass Spectrometry and Application of High-Performance

Objective:Gegen Qinlian decoction(GQD)is a classical traditional Chinese medicine formulation which has been used for almost 2000 years.At Guang'anmen Hospital,Beijing,a modified GQD version(m GQD)with seven instead of four herbal ingredients has been applied to treat Type 2 diabetes.Quality control is a crucial prerequisite for the therapeutic application of herbal medicines.For the identification of products derived from classical GQD,the Chinese Pharmacopeia requires the analysis of only three marker compounds.Because m GQD is a more complex mixture containing seven herbs and hundreds of constituents,the pharmacopoeia method for GQD is inadequate.Materials and Methods:A more comprehensive characterization of the formula's constituents has been developed using ultra-high-performance liquid chromatography-diode array detection(UHPLC-DAD)-Q-Exactive-mass spectrometry(MS)in electrospray ionization positive and negative mode.Moreover,a new method for the fingerprint analysis of m GQD via high-performance thin-layer chromatography(HPTLC)has been established.Results:Altogether,91 compounds have been assigned to their originating plants and 84 substances were identified either by comparison with authentic references or with data from the literature.The HPTLC method is based on the application of two different mobile phases and is able to detect both lipophilic and hydrophilic constituents of m GQD.Conclusions:The modified GQD was extensively characterized by UHPLC combined with DAD and Q-Exactive Orbitrap high-resolution MS detection,leading to the assignment and identification of compounds present in the decoction.In addition,a new method for the fingerprint analysis of the m GQD using HPTLC was established,which allows fast and simple identification of the herbal ingredients in the mixture.
