儿茶酚

It is proposed that the effective in brick tea should be theabrownine, which inhibitory ability is higher than catechins and is closed with theaflavins.

由实验结果分析边茶中的抑制剂不同于红茶和绿茶，可能是茶多酚中的茶褐素，其抑制能力高于儿茶素而接近茶黄素。

Then, catechin monomer was isolated and purified by HSCCC with the purity above 98%.

再以该茶多酚为原料，应用HSCCC分离纯化儿茶素单体，所得EGCG产品的纯度达到98%以上。

The article in recent years the research progress of disease of oral cavity of TP prevention and cure makes one overview. The compositive TP of the basic research 1.1 TP of 1 TP is the floorboard that phenolic apperception of a kind of many hydroxyl closes matter, 25% what hold tea dry weight about, its are main component includes to express gallnut of gallnut catechu element gallnut of element of catechu of gallnut of acerbity ester, watch, watch catechu element is acerbity element of catechu of ester, watch, express gallnut of gallnut catechu element among them acerbity ester content is highest, occupy the 80%[1] of catechu element about, fighting oxidation with its unique element structure, fight the position with fight the respect such as tumor to have choppy, significant. The 1.2 TP absorption in oral cavity and metabolization Lee [2] is measured normally inside a hour after healthy person is chewing green tea Xie Huo contains juice of gargle green tea, content of the TP in saliva is very high, after observing green tea passes salivary enzymatic hydrolyze, TP is slow release and in oral cavity;Yang of local play action [the salivary level after 3] checked 6 volunteers to drink tea, chroma of the TP in making clear the saliva after drinking tea as a result is serous TP pH indicator 2 times, and the salivary TP concentration that contains gargle tea solution a few minutes to be able to produce higher level, and TP can be absorbed through oral cavity mucous membrane.

本文就近年来TP防治口腔疾病的探究进展作一综述。1 TP的基础探究1.1 TP的组成TP是一类多羟基酚类化合物的总称，约占茶叶干重的25%，其主要成份包括表没食子儿茶素没食子酸酯、表没食子儿茶素、表儿茶素没食子酸酯、表儿茶素等，其中表没食子儿茶素没食子酸酯含量最高，约占儿茶素的80%[1]，并以其独特的分子结构在抗氧化、抗突变、抗肿瘤等方面占有重要的地位。1.2 TP在口腔中的吸收和代谢Lee等[2]测得正常健康人在咀嚼绿茶叶或含漱绿茶液后的一个小时内，唾液中TP含量很高，并观察到绿茶通过唾液酶水解后，TP缓慢释放并在口腔局部发挥功能；Yang等[3]检查了6位志愿者饮茶后的唾液水平，结果表明饮茶后唾液中TP浓度是血浆TP浓度的2倍，而含漱茶溶液几分钟即可产生更高水平的唾液TP浓度，且TP可通过口腔黏膜吸收。

Objective To investigate the effects of epigallocatechin gallate and baicalin on human skin fibroblasts from ultraviolet radiation. Methods Fibroblasts were obtained and cultured from human skin.

目的：研究中药活性成分茶多酚单体没食子儿茶素没食子酸酯、黄芩苷对紫外线辐射损伤的成纤维细胞形态、增殖活性及产生IL-6、TNF-α的影响，探讨其光保护作用。

To provide theoretic base for the utilization of heliotrope new shoots of tea trees,biochemical properties of new shoots including the contents of polyphenal,amino acid,flavone and the components of catechin were studied.

为给茶树红紫色芽叶开发利用提供依据，对其部分生化特性，如茶多酚、氨基酸、黄酮类等的含量和儿茶素的组成等进行了研究。

The heliotrope new shoots contain more polyphenal,catechin,flanone and more L-EGCG which is healthful to human beings than the pure green new shoots.

安化群体品种茶树上的红紫色芽叶较纯绿色芽叶含有较多的茶多酚、儿茶素和黄酮类化合物，保健性强的L-EGCG含量亦偏高。

The stronger antioxidant capacity of tea polyphenol is due to the presence of phenolic compounds, such as catechins in its composition.

茶多酚之所以具有很高的抗氧化活性是由于酚类化合物的存在，如在它的结构中存在儿茶素。

The topics which are : high tea catechism system bred; Tea seeds Gleditsia 甙 new biologically active components of the development and use of technology; The anti-allergic reaction compounds TP disease; Barun anti-hypertensive effect of good tea.

其中演讲的题目有：高儿茶素茶系统的育成；茶种子的皂角甙新生理活性成分及其利用技术的开发；茶多酚化合物成分的抗过敏反应症作用；佳巴隆茶的防高血压效果等。

Characteristics of Inclusions: After the tea is kept for a long period of time in a stall and deep fermentation processing begins, the specialties of material and manufacturing make many bioreactions occur for thorough activation of microbes to excrete extra-cellular enzymes, which impacts over 500 stuffs of tea. Theses microbes contain catechin, polyphenols, amylase, cellulose, protein, lipid ,alcohol, ketone, vitamin, microorganism, and organic acid, making them transform, isomerize and degrade, polymerize and couple, so as to produce amylase, thearubigins, theaflavins, cellulose, and microelements that other commercial teas could not produce or produce too little.

三、 内含物的特点：由于原料、制造的特别性，经长期陈化和深发酵的过程，茶叶内含物发生多种生物生化反应，充分激活微生物分泌胞外酶，作用于茶叶中的内含儿茶素、多酚、多糖、纤维素、植物素、蛋白质、脂类、醇类、酮类、维生素、微量元素、有机酸等500多种物质，使之转化、异构降解聚合耦联，生成其他商品茶无法比拟和缺乏的多糖、茶红素、茶黄素、纤维素、微量元素等，并形成以菇稀醇类为主体香气。
