Catechin / ˈ k æ t ɪ k ɪ n / is a flavan-3-ol, a type of secondary metabolite providing antioxidant roles in plants. It belongs to the subgroup of polyphenols called flavonoids. The name of the catechin chemical family derives from catechu, which is the tannic juice or boiled extract of Mimosa catechu (Acacia catechu L.f.). [1]

儿茶素，英文名为Catechin，又名儿茶酸、儿茶精 (Caredhieacid)，系从茶叶等天然植物中提取出来的一类 酚类 活性 物质，分子式为C15H14O6， 相对分子质量 为290.28。 为白色针状结晶（水-醋酸），熔点212~216℃，溶于热水、乙醇、冰醋酸、 丙酮，微溶于冷水和 乙醚，几乎不溶于苯、氯仿及 石油醚。 [1] 儿茶素具有抗肿瘤、抗氧化、抗病菌以及保护心脑器官等多种药理作用，这些药理活性主要由其多羟基结构决定，然而，多羟基结构也使儿茶素在中性和碱性条件下结构 …

兒茶素（ catechin ）又稱兒茶酸 [1] （catechuic acid [2] ）、西阿尼醇（cianidanol [3] ），是多羟基黄烷-3-酚的总称，含2,3–位构型不相同的4个异构体，屬於黃烷醇類物質。可由儿茶中提取，为无色结晶形固体，能溶于水。

Catechin 以剂量依赖的方式防止时间诱导的情景记忆缺陷，最有效的剂量为 200 mg/kg，口服。 与 DOX 单独处理组相比，Catechin 处理可防止 MPO 水平升高 (海马体和额叶皮质分别为 21.98±9.44 和 36.76±4.39%) [3] 。

Tea, a product obtained from the leaves and buds of the plant Camellia sinensis, is one of the richest catechin sources and contains, as the major catechin, (−)-epigallocatechin-3-gallate (EGCG) (Figure 1) which has many beneficial properties for human health such as anticancer, anti-obesity, antidiabetic, anticardiovascular, anti-infectious, he...

2014年4月29日 · 兒茶素（Catechin），俗稱茶單寧，兒茶酚，是多羥基黃烷-3-酚的總稱，兒茶素是茶多酚類(Polyphenol)中最重要的一種，在綠茶中含量較高。 它是無色、溶於水的化合物是茶的苦澀味的來源之一。 兒茶素及氧化產物均是碳氫氧三元化合物(C15H14O6)，經由糖類一系列酶的作用，通過莽草酸途徑(shikimate pathway)，形成苯環化合物，以及最後合成兒茶素。 兒茶素含有特別的酚，約75％〜80％的多酚含量，可使重金屬和蛋白質沉澱，將生皮鞣成革性能，又稱 …

Catechins are polyphenols found in green tea that exhibit neuroprotective activities by activating protein kinase C and transcription factors, inducing the expression of cell-survival genes, suppressing processes related to Alzheimer's disease, and activating signaling pathways for cell-survival and anti-inflammatory actions.
