A major discovery of Yunnan Agricultural University in China: EGCG, the active ingredient in tea, can strongly bind to S protein of new coronavirus and effectively block the binding of S protein of new coronavirus to human ACE2 receptor.

EGCG（Epigallocatechin gallate）, Chinese alias: green tea extract; epigallocatechin gallate, which is the main constituent of green tea polyphenols, is a catechin monomer isolated from tea. It has antibacterial, antiviral, antioxidant, Anti-arteriosclerosis, anti-thrombosis, anti-angiogenesis, anti-inflammatory, and anti-tumor effects.

The anti-tumor effect of tea polyphenols has been recognized by relevant researchers at home and abroad. Studies have shown that its main component catechin (accounting for 70% to 80% of total tea polyphenols) plays a major role. In recent years, scientists have increasingly focused on catechins, especially one of the monomers, epigallocatechin gallate (EGCG), which is the most striking. EGCG is catechin specific to tea, with the highest amount, accounting for 40% to 50% of tea polyphenol products. It is an ester of 2-continuous phenol benzopyran and gallic acid. It has the versatility of phenolic antioxidants and has many properties superior to other catechins because of its 6 ortho-phenolic hydroxyl groups in its structure.

Guidance on the nutritional diet for the prevention and treatment of pneumonia caused by new coronavirus is aimed at the clinical nutrition diet of patients with pneumonitis (general or rehabilitation) of new coronavirus infection.
