Abstract: Tea is a leafy perennial crop, and its physiological metabolism is significantly affected by external environmental factors. Main biochemical components such as amino acids, caffeine and tea polyphenols not only give tea unique flavor quality and health characteristics, but also are important contributors to the resistance of tea plants to biotic and abiotic stresses. Metabolomics technologies have the characteristics of high throughput, high sensitivity and systematization. They can identify and quantify tea metabolites comprehensively, accurately and quickly. The in-depth study of metabolomics provides a technical platform for the further development and utilization of tea metabolites. This paper reviewed the applications of metabolomics in the study of physiological and biochemical metabolism (photosynthesis, respiration, carbon and nitrogen metabolism) and metabolism of main quality biochemical components (flavonoids, alkaloids, amino acids, etc.) of tea plants in recent years, and prospected the future applications of metabolomics in the field of tea, so as to provide some theoretical references for further tea management, cultivar breeding and quality improvement.

Key words: metabolomics, Camellia sinensis, physiology and biochemistry, metabolites
