儿茶素是茶叶保健功能的主要物质基础，具有抗菌作用、抗突变、抗癌和保护神经系统等功效，但存在储存稳定性差，生物利用度率低等问题，对儿茶素进行糖苷化结构修饰是提高其稳定性和生物利用度的有效途径之一。对儿茶素不同位点的糖苷化修饰方法进行综述，为儿茶素的相关研究及应用提供参考。

Catechins, the main component of tea health care function, are flavonoids with strong physiological activities, such as broad spectrum bacteriostatic activity, anti-mutation, anti-cancer effects and the protection of the nervous system, which has been one of the hot research topics during recent years. But the storage stability and the oral bioavailability of catechins are relatively low. Glycosylation is one of the effective ways to improve the stability and bioavailability of catechins to some extent. In order to promote the further study and application of catechins, the glycosidic methods at different sites of catechins were summarized in this paper.
