Tea pigment has pharmacological effects such as anti-lipid peroxidation, enhancing immunity, reducing blood lipid, bidirectional regulating blood pressure and blood lipid, anti-atherosclerosis, reducing blood viscosity, improving microcirculation and inhibiting experimental tumors.

Before 1990, only 0.6- 1.6 kg of tea pigment can be extracted per ton of tea, which is known as "green gold in medicine". Now, with the development of purification technology, the purity can reach 99. 1% (the test results are subject to the tea quality supervision, inspection and testing center of the Ministry of Agriculture), and at the same time, the ability to produce high-purity tea pigments on an industrial scale has been realized.

Main components of tea pigment

Tea brown pigment is the main component of tea pigment, and its content accounts for more than 85% of the total tea pigment. It is a heterogeneous group of phenolic oxidized polymers, from which catechin dimers, oligomers and a small amount of polymers are detected.

Tea polyphenols are the general name of phenolic substances and their derivatives in tea, accounting for about 20% ~ 35% of the total tea. After oxidative polymerization, some tea polyphenols can be converted into tea pigments. Tea pigment has high activity and unstable structure, which will change with the change of temperature and time.
