Abstract

Tea polyphenols are the most abundant active components in tea, with a variety of physiological functions. However, there is a lack of a systematic summary regarding the research history of tea polyphenols. This paper systematically reviewed the discovery, naming and functional application of tea polyphenols, while also briefly discussed their health benefits in immune regulation, anti-inflammation, and oxidative stress as well as the structural basis of the active hydroxyl groups in polyphenols. Consequently, it provided support for the application research of tea polyphenols in different fields. In addition, in view of the problems of poor stability and low bioavailability of tea polyphenols, we provided a brief overview of research on novel tea polyphenol nanobiomaterials. These nanobiomaterials exhibited the characteristics of high stability, safety and multi-functionality, which were anticipated to enhance the further application of tea polyphenols.
