In addition, ice grape wine also contains human metabolism of amino acid, the red wine polyphenols compound can dilate blood vessels, hemal wall keep elasticity and improve KuoZhangLi capillary, kill bacteria or germs.

另外，冰酒还含有人体代谢所需的氨基酸，红冰酒中的多酚类化合物能扩张血管，使血管壁保持弹性，提高毛细血管的扩张力，杀死细菌或病菌。

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。

To assess the sensitivity of local species to toxic chemicals relative to those from other jurisdictions reported in the literature, ecotoxicological testing was also performed on three local marine species, Dunaliella salina, Brachionus plicatilis, and Lutjanus malabaricus, using 12 representative PPTSL chemicals including metals, pesticides (endosulfan, diazinon, permethrin, atrazine, tributyltin), and industrial chemicals (di-n-octyl phthalate, nonylphenol, acenaphthene).

为了评估与其他相关成文规定的当地有毒化学品种类，生态毒性测试也在三个地方的海洋物种上进行，杜氏盐藻，轮虫和红鳍笛石斑鱼，使用了十二种pptsl代表的化学元素，包括金属，杀虫剂（硫丹，二嗪磷，氯菊酯，莠去津，三丁基锡），和工业化学品（苯二甲酸二正辛酯，壬基酚，苊）。

Two hundred 16-day-old of age commercial broiler chickens were randomly divided into 4 groups as follows: 50 birds were exposed to normal temperature (20℃) and peritoneally injected with normal saline as control group; 50 birds were exposed to low temperature (7-9℃) and peritoneally injected normal saline as low temperature group; 50 birds were exposed to low temperature and peritoneally injected with low dose BQ123 as low temperature low dose BQ123 group; 50 birds were exposed to low temperature and peritoneally injected high dose BQ123 as low temperature high dose BQ123 group.

本试验采用高选择性ETA受体拮抗剂BQ123预处理低温肉鸡，探讨ET在低温诱发AS模型的肺血管重塑和肺动脉高压发生发展中的作用。200只16日龄AA肉鸡随机均分为4组：常温(20℃)对照组、低温(7～9℃)对照组、低温低剂量BQ123组和低温高剂量BQ123组。23日龄、30日龄时进行肺动脉压的测定，肺组织取材、石蜡切片，Weigert间苯二酚复红染色。

Results:The leaves of Tatarian Dogwood contained amino acid,polysaccharides,reducing sugar,glycosides,cardiac glycosides,anthraquinones,flavonoids,tannin,volatile oils and chlorophyll.Protein,organic acid,coumarin and alkaloid failed to be detected.

结果：红瑞木叶含有氨基酸、多糖、还原糖、苷类、酚性物、蒽醌、黄酮、鞣质、挥发油、叶绿素等化学成分，未检测出蛋白质、有机酸、香豆素、生物碱、皂苷类成分。

In the paper,the fresh,withered,rocked and fermented leaf fixed by microwave and steam were studied.The results showed that the content of pol yphenols of microwave samples was higher than those of steam samples;and the con tent of amino acids in steam samples was higher than those of microwave samples .There was a slight higher content of soluble sugars in microwave samples compa red with steam samples. The content of chlorophyll of microwave samples was hig her than steaming samples,and there was a small difference of caffeine content b etween microwave and steam samples.There was a little higher content of theafla vins in microwave samples than steam samples.The content of thearubigins in steam samples was higher than microwave samples,and there was no differe nt theabrown between microwave and steam samples.

摘 要：对鲜叶、萎凋叶、做青叶和发酵叶进行了微波和蒸青固样研究，结果表明：微波样的多酚类化合物保留量均高于蒸青样，氨基酸保留量则相反，可溶性糖的保留量微波样稍高于蒸青样，叶绿素的保留量微波样亦稍高于蒸青样，咖啡碱的保留量微波样与蒸青样间差异较小，发酵叶茶黄素的保留量微波样稍高于蒸青样，发酵叶茶红素的保留量微波样高于蒸青样，发酵叶茶褐的保留量二者间无差异。

The red vine leaf is harvested when the leaves have the highest content of nutrients, including 10% polyphenols and flavonoids.

红葡萄叶收获时，叶片的养分含量最高，包括10 ％的茶多酚和黄酮类化合物。
