一般描述

(−)-表儿茶素(EC)属于黄烷醇类化合物，在可可和可可产品中大量存在。表儿茶素的化学结构由1个4-羟基含氧杂环连接2个苯环组成。

应用

(−)-表儿茶素(EC)已用于：
  • 在体内（高脂喂养小鼠）和体外（HepG2细胞）研究中，作为抗氧化剂下调烟酰胺腺嘌呤二核苷酸磷酸(NADPH)氧化酶水平和提高胰岛素敏感性。
  • 研究其对边缘高血压大鼠(BHR)模型血压、一氧化氮合酶(NOS)活性和类焦虑行为的影响
  • 使用氧化应激参数检测其对游泳训练中的中年小鼠海马体神经元存活情况的影响。
  • 研究其在黑巧克力中的抗氧化性
  • 作为多酚分析的特征化合物

生化/生理作用

表儿茶素可增强心力衰竭患者的骨骼肌结构，最大限度降低心脏代谢风险。可用于治疗肌肉减少症。表儿茶素减少肌肉生长抑制素和 β-半乳糖苷酶，提高肌肉生长标志物水平。
