So far, more than 700 known compounds have been isolated and identified from tea. These include primary metabolites such as proteins, carbohydrates, and lipids, as well as secondary metabolites such as polyphenols, pigments, theanine, alkaloids, aroma substances, saponins, etc. Catechins are an important component of the secondary metabolism of tea plants and are also the main component of tea with health benefits. In recent years, a large number of studies at home and abroad have found that catechins have many functions such as scavenging free radicals in the body, antioxidation, inhibiting tumor growth, preventing radiation, antibacterial and disinfection, and reducing toxic effects. As raw materials for health foods, natural cosmetics, or antioxidants for preserving the freshness of oily foods, it has been widely used in the fields of medicine, daily chemical industry, food and oil industry.
