Abstract:

Flavonoids are the major secondary metabolites with diverse biological activities in high plant. As one of the main subgroups of flavonoids, catechins usually account for 12%-25% dry weight in fresh leaves of tea plant [Camellia sinensis (L.) O. Kuntze]. Catechins are not only the most important components in tea flavor, but also possess a lot of physiological functions, such as antioxidant activity, antimutagenic and anticarcinogenic potential ,anti-cardiovascular diseases, anti-ultraviolet radiation and so on. This paper reviewed the progresses in the flavonoids or tea catechins branch pathway and regulation, subcellular localization and organization of flavonoid enzymes, and may provide additional insights into regulating gene expression and engineering the catechins biosynthesis in tea plant.

Key words: flavonoids, tea, catechins, biosynthesis pathway, regulation
