茶褐素的组成结构与功能活性研究进展

Research progress in composition structure and functional activity of Theabrownin

摘要: 茶褐素是由茶黄素和茶红素进一步氧化聚合而成的褐色高聚物,其结构中含有羟基、羧基、烷基和苯环类似物等,具较强的抗氧化、抗癌、降血脂等功效。本文综述了茶褐素的组成结构、形成与积累和功能活性;最后,提出茶褐素在当前研究中面临的困境,并进行了展望。

Abstract: Theabrownin is a brown polymer which is formed by the further oxidation and polymerization of theaflavin and thearubigins; in terms of its structure, it contains hydroxyl, carboxyl, alkyl and benzene analogs, so it is endowed with relatively strong antioxidant, anticancer, reducing blood lipid and other efficacy. This paper summarizes the composition structure, formation and accumulation, and functional activity.Finally, puts forward the difficulties confronted in the current research and envisions its prospect.
