Research progress on glycosidation modification of catechins / 中草药

ABSTRACT

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.
