简介：在忍冬装饰用的梨树花的di-O-caffeoylquinic酸(diCQAs)的三种类型的抗菌剂活动，繁体中文药(TCM)，在杆菌shigae上，生长被microcalorimetry调查并且比较。diCQAs的三种类型是3，4-di-O-caffeoylquinic酸(3，4-diCQA)，3，5-di-O-caffeoylquinic酸(3，5-diCQA)，并且4，5-di-O-caffeoylquinic酸(4，5-diCQA)。新陈代谢的力量时间上的三diCQAs的效果的质、量的信息弄弯的一些，生长率常数k，最大的热产量力量下午，和产生预定tG，全部的热产量Qt，和生长禁止的比率我B。shigae是计算的。根据一个thermo运动的模型，k，下午，Qt，我和c的相应量的关系被建立。另外，这些药(IC50)的一半禁止的集中被定量分析获得。基于数量活动关系和IC50价值，禁止的活动的顺序是3，5-diCQA>4，5-diCQA>3，4-diCQA。结果说明在C-5的caffeoyl酉旨组是为细菌的房间有一种更高的亲密关系的主要的组的可能性，并且二caffeoyl酉旨的intramolecular距离组织，这也在diCQAs的抗菌剂活动有重要影响。

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。
