【摘要】：目的通过应用色谱-质谱联用分离检测技术,对左金丸和香连丸及组成单味药的挥发油和生物碱的化学成分进行定性分析;并对左金丸和香连丸的化学成分进行网络药理学研究,探索其抗腹泻、胃溃疡和溃疡性结肠炎作用的多成分-多靶点-多通路的作用机制。方法本研究采用气相色谱-质谱联用和液相色谱-质谱联用两种分离检测技术,通过对左金丸和香连丸及组成单味药的挥发油成分和生物碱类成分提取物的分离检测,获得其色谱质谱数据,并结合数据库和文献对其化学成分进行鉴定;通过PharmMapper服务平台、TTD和DrugBank数据库建立多成分-多靶点网络,采用MAS在线分析系统进行GO富集和KEGG通路注释分析,然后利用Cytoscape软件构建左金丸和香连丸抗腹泻、胃溃疡和溃疡性结肠炎的多成分-多靶点-多通路的网络模型并加以分析。结果挥发油部分左金丸共鉴定出63种化合物,香连丸鉴定出76种化合物;单味药黄连、吴茱萸、木香分别获得80、78、76种化合物。醇提取物提取部分左金丸和香连丸中鉴定出黄连碱、药根碱、小檗碱、巴马汀、去氢木香内酯、木香烃内酯、吴茱萸次碱和吴茱萸碱。网络药理学分析预测出左金丸中有30个活性成分作用于10个靶点,关联到27条通路;香连丸中有45个活性成分作用于12个靶点,涉及28条通路。结论本研究从挥发油和醇提取物两方面比较全面地阐释了左金丸和香连丸所含有的化学成分组成,构建出的左金丸和香连丸的抗腹泻、胃溃疡和溃疡性结肠炎的网络模型体现出药对多成分、多靶点、多通路的作用机制,为药对左金丸和香连丸的物质基础和药理作用机制的深入研究提供了科学依据。
[Abstract]:Objective to analyze qualitatively the chemical constituents of volatile oil and alkaloids in Zuojin pills and Xianglian pills by chromatography-mass spectrometry.The chemical constituents of Zuojin Pill and Xianglian Pill were studied by network pharmacology to explore the mechanism of its action against diarrhea, gastric ulcer and ulcerative colitis.Methods Gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) were used to separate and detect the volatile oil and alkaloid components of Zuojin pills and Xianglian pills.Obtaining its chromatography-mass spectrometry data and identifying its chemical constituents in combination with databases and literature; establishing multi-component and multi-target networks through the PharmMapper services platform TTD and DrugBank databases,Go enrichment and KEGG path annotation analysis were carried out by MAS online analysis system. Then the network model of Zuojin Pill and Xianglian Pill against diarrhea, gastric ulcer and ulcerative colitis was constructed and analyzed by Cytoscape software.Results A total of 63 compounds were identified in Zuo Jin Pill, 76 compounds were identified in Xianglian Pill, and 80 Rhizoma Coptidis, Evodia rutaecarpa and Euphorbia were obtained respectively.Coptis alkaloids, root alkaloids, berberine, berberine, Bamatin, dehydroxyxycarbenolide, xylvanolactone, rutaecarpine and rutaecarpine were identified by alcohol extract from Zuojin pills and Xianglian pills.Network pharmacological analysis predicted that there were 30 active components acting on 10 targets in Zuojin pills, which were related to 27 pathways, and 45 active components in Xianglian pills acted on 12 targets, involving 28 pathways.Conclusion the chemical constituents of Zuojin Pill and Xianglian Pill were explained comprehensively from the aspects of volatile oil and alcohol extract, and the anti-diarrhea of Zuojin Pill and Xianglian Pill were constructed.The network model of gastric ulcer and ulcerative colitis shows the action mechanism of drug on multi-component, multi-target and multi-pathway, which provides scientific basis for the further study of the material basis and pharmacological mechanism of Zuo Jin Pill and Xianglian Pill.
