Abstract: Tea biochemistry is a subject of life science on Camellia Sinensis. It mainly focus on characteristic secondary metabolites of tea plants, especially those in the fresh tea shoots using biochemical and molecular techniques as research tools. Those metabolites include catechins, caffeine, theanine and volatile terpenes, which contribute greatly to tea quality and healthy effects. The major research fields of tea biochemistry involve the biosynthesis of secondary metabolites in tea plants, their transformation during tea processing and their effects on final tea quality and healthy function. Recently, there have several breakthroughs in the metabolites biosynthesis pathway, tea genome, specific tea germplasm metabolome, the processing metabolome, as well as the chemistry of tea quality. Since tea biochemistry is the fundamental in tea science, its achievements provide the theoretical basis and method approaches to tea cultivation and breeding, tea primary and further processing, tea trading and tea culture. With the development of tea industry and life science & technology, it is believed that the advancement of tea biochemistry will push forward tea industry to a high level at the sustainable development.

Key words: tea biochemistry, secondary metabolism, genome, metabolome, processing chemistry, quality chemistry
