Ferruzzi is currently conducting a study examining whether citrus juices and vitamin c increase catechin absorption in lab animals 费鲁齐目前正在从事一项研究，在实验室动物身上研究柑橘类果汁和维生素c是否能增加儿茶素的吸收水平。
Tea polyphenols , fluoride and aluminum are important substances in tea plant , and they are also the focus of tea infusion concerning human health 儿茶素、氟和铝是茶树体内的重要物质，涉及到茶树生理上的物质运输，茶的饮用与保健诸方面。
Tps demonstrated profound biochemical and pharmacological including antioxidant activities , modulation of carcinogen matabolism and inhibition of cell proliferation 其中以egcg的含量最高，占儿茶素的50左右。对茶及tps的药效研究已有大量文献报道。
Polymerization of al - catechin complexes may reduce aluminum absorption in intestine . f " can compete a13 + with catechins in solution , and its ability become stronger with decreasing of ph value 氟能够与儿茶素竟争性的与a广络合，在较低的ph值时，氟的竞争性增强。
The study found that a substance in green tea , a major polyphenol called epigallocatechin gallate ( egcg ) has the ability to block the hiv virus from attacking the immune system 该研究发现绿茶中主要的一种茶多酚，表没食子儿茶素没食子酸酯（ egcg ） ，能够阻止hiv病毒攻击免疫系统。
The catechins are responsible for the slightly astringent , metallic taste of green tea beverage . they are involved also in browning and other types of discoloration in foods of plant origin 儿茶素是绿茶饮料略带收敛性金属味的主要根源，也与植物性食品的褐变和其它类型的变色有关。
A mixture of catechin and epicatechin , procyanidin b4 , 4 - hydroxy - benzoic acid and ethyl gal - late were purified and identified from grape seed procyanidin extract 得到2种原花青素的单体： ( + ) -儿茶素和( - ) -表儿茶素； 1种原花青素二聚体b4 ； 2种其他酚类物质：对羟基苯甲酸及没食子酸乙酯。
The antioxidants in question are called catechins , believed to be responsible for some of green tea ' s reported health benefits , such as reducing the risk of cancer , heart attack and stroke 被研究的抗氧化剂名为儿茶素，被认为是绿茶中对身体有益的物质，如减少患癌症、心脏病和中风的风险。
For this property , catechins may play an important role in affecting the bioactivity of aluminum in tea infusion . some related research work has approved the function 儿茶素、茶多酚对铝的这种作用，可能在影响铝的生物学活性方面起着重要作用，相关的研究也证实了儿茶素、茶多酚的这种作用。
It was found that the levels of catechins and proanthocyanins in those subclones accumulating anthocyanins were also raised , and were independent of the activity of phenylalanine ammonia - lyase 发现积累色素的细胞系中，儿茶素与原花色素的形成能力也得到了大幅度提高，且与苯丙氨酸解氨酶活性无关。
