摘要
采用超高效液相色谱-飞行时间质谱联用技术(UPLC-Q-TOF-MS/MS)分析干姜和炮姜的化学成分差异,并结合网络药理学初步探究其功效差异的潜在机制。通过UPLC-Q-TOF-MS/MS分析干姜和炮姜中化学成分,应用偏最小二乘法判别分析(PLS-DA)和随机森林(RF)筛选差异化合物;借助SuperPRED和GeneCards数据库分别获取药物靶点和疾病靶点,并通过维恩图映射出药物靶点与疾病靶点的共同靶点;借助STRING数据库构建PPI网络图,借助DAVID数据库对关键靶点进行GO和KEGG富集分析。UPLC-Q-TOF-MS/MS分析指认出61个化学成分,筛选出7-Gingerol、12-Gingerol和Gingerenone A等13个差异化合物;网络药理学结果提示,干姜主要作用于MAPK1、PTGS1和OPRD1等靶点,介导白细胞介素-17、Toll样受体和TNF等信号通路的表达,缓解炎症反应,以发挥温中止痛之功效;炮姜主要作用于APEX1、SLC6A5和NFKB1等靶点,介导HIF-1信号通路、神经营养因子信号通路和细胞凋亡等,阻断疼痛信号传导,发挥温中散寒之功效。通过化学成分差异分析结合网络药理学方法,初步探讨了干姜和炮姜的功效差异的潜在机制,为其临床应用提供一定的科学依据。
Ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS)was used to analyze the differences in chemical composition of dried and baked ginger.Then,network pharmacology was applied to investigate the mechanisms underlying their differences in efficacy.The chemical components of dried and baked ginger were analyzed using UPLC-Q-TOF-MS/MS,and the differential compounds were screened using partial least squares-discriminant analysisand random forest methods.SuperPRED and GeneCards databases were employed to retrieve drug and disease targets,respectively.Common targets were identified using Venn diagram mapping.Protein-protein interaction networks were constructed using the STRING database,and key targets were subjected to GO and KEGG enrichment analyses using the DAVID database.The UPLC-Q-TOF-MS/MS identified 61 chemical components,screening out 13 differential compounds(e.g.,7-gingerol,12-gingerol,and gingerenone A).The network pharmacology results revealed that dried ginger mainly acts on targets such as MAPK1,PTGS1,and OPRD1,mediating the expression of signaling pathways such as interleukin-17,toll-like receptor,and TNF to alleviate inflammatory responses,exerting a“warming the middle to relieve pain”effect.Baked ginger mainly targets APEX1,SLC6A5,and NFKB1,mediating the HIF-1 signaling pathway,neurotrophin signaling pathways,and apoptosis to block pain signal transmission,exerting a“warming the middle to dispelling cold”effect.By integrating chemical composition analysis and network pharmacology,this study elucidated the mechanisms underlying the distinct therapeutic effects of dried and baked ginger,providing a scientific basis for their clinical applications.
