The secret of green tea lies in the fact it is rich in catechin polyphenols, particularly epigallocatechin gallate.

绿茶的秘密在于它富含儿茶素，特别是没食子儿茶素没食子酸酯。

目的 研究儿茶素的抗氧化活性，儿茶素微胶囊的制备工艺及其对大鼠肾病综合征的疗效。

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。

The anti oxidation and preservative effects of tea catechins added to feed of chicken were investigated in this study.

通过在肉鸡饲料中添加一定量的儿茶素，来研究体内儿茶素对鸡肉的抗氧化保鲜作用效果。

Upon initial signal assignment, about 20 chemical constituents in tea were identified, including amino acids, theanine, catechins (EGC, EC, EGCG, ECG and unknown catechins), sucrose, unknown sugars, fatty acids, caffeine, quinic acid and so on. The NMR data were then analyzed by the principal component analysis technique.

检测出约20种物质，包括多种氨基酸、茶氨酸、多种儿茶素表没食子儿茶素(EGC、表儿茶素、表没食子儿茶素没食子酸酯、表儿茶素没食子酸酯和一些未知的儿茶素、蔗糖、未知糖类、脂肪酸、咖啡因等。

These include catechin and gallocatechin (hydroxyls at positions 5' as well as at 3' and 4' as in catechin), their esters with gallic acid, catechin gallate, and gallocatechin gallate, and their epimers.

它们有几茶素和儿茶素(在5'位上以及如同儿茶素中一样在3'和4'位上羟基化)，它们与酸生成的酯，即儿茶素酸酯和儿茶素酸酯，以及它们的差向异构体。

There are more catechins contanted in old leaf than in the tender leaf that was used for manufacturing tea. In this study, we propose a process to extract the catechins from the waste old tea leaf, eliminate the caffeine from the extract and assess the functional effects of the product.

然而制茶中所采用的嫩叶内儿茶素的含量反而较茶农修剪茶树所遗弃的老叶内之儿茶素含量为低，故本研究的目的在於利用茶农修剪茶树后废弃的老叶做为原料，而於从老叶提取儿茶素的过程中去除咖啡因，并对其进行抗氧化以及抑制人类癌症细胞株生长等功能性评估。

Procyanidin contents of 5 cultivars were 8.46-13.90 mg·g~(-1), and 'Golden Delicious' was found to contain much more procyanidins followed by 'Jonagold'.

原花青素是一类聚多酚类物质，由不同数量的儿茶素、表儿茶素或儿茶素与表儿茶素缩合而成。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.
