Epigallocatechin

Epigallocatechin is a type of catechin, which is a natural phenol and antioxidant. It is a plant secondary metabolite. It belongs to the group of flavonoids which are known for their numerous health benefits. Epigallocatechin is commonly found in various types of tea, especially green tea, and it is also present in small amounts in wine, fruits, nuts, and chocolate.

Structure and Properties

Epigallocatechin is a type of flavan-3-ol, a class of flavonoids. It is a stereoisomer of catechin and has two chiral centers, hence it has four diastereoisomers. The structure of epigallocatechin consists of two benzene rings (A and B) and a dihydropyran heterocycle (C) with a hydroxyl group on carbon 3. The A ring is similar to a resorcinol ring while the B ring is similar to a catechol ring.

Sources

The primary dietary source of epigallocatechin is green tea. Other sources include certain types of fruits, nuts, and chocolate. The highest concentration of epigallocatechin is found in the dried leaves of green tea (7380 mg per 100 g).

Health Benefits

Epigallocatechin has been studied for its potential health benefits. It has been found to have antioxidant, anti-inflammatory, and anticancer properties. It may also help to improve heart health, support weight loss, and protect against neurodegenerative diseases.

Research

Research on the health benefits of epigallocatechin is ongoing. Some studies suggest that it may help to prevent certain types of cancer, including breast and prostate cancer. Other research indicates that it may help to reduce inflammation and oxidative stress, which are linked to many chronic diseases.
