General description

儿茶素是植物化学物质，在黑葡萄、桃子、草莓和蚕豆中含量丰富。儿茶素有各种形式，如儿茶素、表儿茶素、表儿茶素没食子酸酯、表焙儿茶素和表没食子儿茶素没食子酸酯。

Application

(+)-水合儿茶素已用于以下情形：
  • 作为多酚标准品，测定红葡萄酒副产物中的多酚总量
  • 作为添加剂，通过三重进料批量方法研究对体外甲烷生产和底物降解的效果
  • 作为底物，测定L. plantarum CECT 748T 14重组鞣酸酶对儿茶素的活性

Biochem/physiol Actions

一种植物来源的抗氧化性黄酮类化合物；自由基清除剂，可在各种生物系统中防止自由基介导的损伤。例如，在生理pH条件下，儿茶素可抑制羟基自由基介导的DNA链断裂。它还可以防止人体血浆氧化。它延迟了内源性脂溶性抗氧化剂的消耗并抑制脂质氧化。儿茶素还可以作为脂肪酸合酶的抑制剂。

Catechin hydrate is a phytopharmaceutical with promising anticancer effects but poor bioavailability. This study aimed to elaborate catechin loaded chitosan-tethered liposomes (chitosomes) to enhance catechin oral bioavailability. Nanocarriers were optimized via ethanol injection method followed by physicochemical, ex vivo and

Increases in the environmental osmolarity are key determinants for the growth of microorganisms. To ensure a physiologically acceptable level of cellular hydration and turgor at high osmolarity, many bacteria accumulate compatible solutes. Osmotically controlled uptake systems allow the scavenging of
