中文摘要：

传统中医理论认为,广东凉茶具有清热祛湿等多种功效.但由于其成分异常复杂,难以利用传统评价手段对其作用机制进行全面分析.文中引入代谢组学的研究策略,即采用稳定性和重复性俱佳的核磁共振技术（NMR）获得大鼠血清样本中代谢物指纹图谱的＂全景＂数据,然后对其进行多元数据分析,识别差异标志物.结果表明,长期饮用广东凉茶使大鼠体内的脂类代谢、糖代谢及能量代谢发生变化,且其代谢响应呈现阶段性特征.本研究为深入解析广东凉茶的作用机制和建立科学的凉茶评价系统提供了实验依据.

英文摘要：

As pointed out by the traditional Chinese medicine theory, Cantonese Herbal Tea （CHT） is of various functions such as heat clearing and dampness removing. However, the corresponding action mechanism is hard to evaluate through traditional assessments due to its extremely complex components. In order to solve this problem, the NMR technology with stability and repeatability is employed to obtain the panoramic view of the fingerprints of the metabolites in the serum of rats, and a multivariate data analysis as well as an identification of discriminative bio- markers is carried out. It is found that long-term CHT intake modulates the metabolisms of fats, carbohydrates and energy in rats in a stage form. This study provides an approach to the deep analysis of action mechanism of CHT and to the construction of a scientific evaluation system of CHT.
