Black tea is not only rich in catechins, tea pigments, flavonoids, vitamin C, vitamin E, D- carotene and other antioxidant substances, but also contains a large number of trace elements with antioxidant effects such as zinc, manganese, copper and selenium. Catechins, theaflavins, theanine and tea polysaccharides in black tea, especially compound flavonoids with high content, all have the function of scavenging free radicals, so they have the functions of antioxidation and delaying cell aging.
