摘要
通过建立杜仲不同部位HPLC指纹图谱分析方法,结合网络药理学预测杜仲潜在质量标志物。基于中药质量标志物(Q-Marker)的理论依据,结合指纹图谱和网络药理学对杜仲Q-Marker进行初步预测分析,对63批杜仲不同部位样品进行相似度评价,同时分别进行主成分分析(PCA)及偏最小二乘法判别分析(PLS-DA);通过网络药理学筛选杜仲相关成分的靶点和通路,构建“成分-靶点-通路”网络图,预测杜仲的Q-Marker。本研究建立了63批杜仲不同部位的指纹图谱,相似度均大于0.900,经筛选得到8个化合物,173个靶点,包括PIK3R1、HRAS、AKT1、EGFR、SRC等11个核心靶点,涉及氨代谢、癌症通路、脂质和动脉粥样硬化、癌症蛋白聚糖、PI3K-Akt信号通路、卵巢类固醇生成等主要通路,并构建成分-靶点-通路图。预测绿原酸、芦丁、京尼平苷为杜仲叶潜在Q-Marker,桃叶珊瑚苷、京尼平苷酸、松脂醇二葡萄糖苷为杜仲皮潜在Q-Marker,京尼平苷酸、京尼平苷、桃叶珊瑚苷为杜仲雄花潜在Q-Marker,将绿原酸、京尼平苷酸、桃叶珊瑚苷为杜仲果荚潜在Q-Marker。
The potential mass markers of Eucommia ulmoides were predicted by establishing an HPLC fingerprint analysis method for different parts of E.ulmoides combined with network pharmacology.Based on the theoretical basis of traditional Chinese medicine(TCM)quality markers(Q-Marker)combined with fingerprint mapping and network pharmacology for primary prediction analysis of Q-Marker of E.ulmoides,63 batches of samples from different parts of E.ulmoides were evaluated for similarity,along with principal component analysis(PCA)and partial least squares discriminant analysis(PLS-DA),respectively;Through network pharmacology to screen the targets and pathways of related ingredients in E.ulmoides,a‘ingredient target pathway’network diagram was constructed to predict Q-Marker in E.ulmoides.In this study,we established 63 batches of fingerprints from different parts of E.ulmoides with similarity scores greater than 0.900,which were screened to obtain eight compounds and 173 targets,including 11 core targets including PIK3R1,HRAS,AKT1,EGFR,SRC,and other major pathways involved in ammonia metabolism,cancer pathways,lipids and atherosclerosis,cancer proteoglycans,PI3K Akt signaling pathway,and ovarian steroidogenesis,and constructed component target pathway maps.Chlorogenic acid,rutin and geniposide were predicted to be potential Q-Marker for E.ulmoides leaves,aucubin,geniposidic acid and pinoresinol diglucoside were predicted to be potential Q-Marker for E.ulmoides bark,geniposidic acid,geniposide and aucubin were predicted to be potential Q-Marker for E.ulmoides male flower,chlorogenic acid,geniposidic acid,aucubin were identified as potential Q-Marker for E.ulmoides pods.
