  • 简介:Chuanwu(CW),从AconitumcarmichaeliiDebx的母亲根的著名繁体中文药(TCM)……(Ranunculaceae),被用于各种各样的疾病的处理。不幸地,因为它的狭窄的治疗学的窗户,它的毒性经常被报导。在现在的学习,一个metabolomic方法被执行描绘phenotypically生物化学的不安和导致CW的毒性的潜在的机制。同时,在尿的毒性biomarkers的表示水平被分析与Gancao由联合评估detoxification(根值Glyeyrrhizae,CG),Baishao(根值PaeoniaeAlba,CS)并且Ganjiang(根茎Zingiberis,CJ),它从古典TCM药方被屏蔽。尿metabolomics被UPLC-Q-TOF-HDMS,和集体系列执行检测代谢物的信号系统地用模式识别方法被分析。作为结果,与CW毒性联系的十七biomarkers被识别,它与戊糖和glucuronate被联系互变现象,丙氨酸,aspartate,和glutamate新陈代谢,在其它之中。大多数毒性biomarkers的表示层次被相容性药有效地向正常范围调制。它显示三相容性药能有效地除去CW。在摘要,我们的工作证明metabolomics为TCM对毒性和发现detoxification方法的评估极其重要。
