    Green tea extract/Polyphenols/EGCG Green Tea Extract
    Green tea extract is a kind of herbal derivative extracted from green tea (Camellia sinensis). It contains catechins (GTC). Green tea and its derivatives can be used as dietary supplements.

    Epigallocatechin gallate (EGCG), also known as epigallocatechin-3-gallate, is the ester of epigallocatechin andgallic acid, and is a type of catechin. EGCG, the most abundant catechin in tea, is a polyphenol under basic research for its potential to affect human health and disease. EGCG is used in many dietary supplements.

    EGCG Extract is the main component of green tea polyphenols and is a catechin monomer isolated from tea leaves. Its highest amount is 40% -50%. At the same time, it has many properties superior to other catechins because of its 6 ortho-phenolic hydroxyl groups in its structure.

    EGCG is a kind of component extracted from Chinese green tea. It is the primary active and water-soluble component of green tea, which has the highest content among the tea catechins. By virtue of its peculiar stereochemical structure, EGCG possesses much stronger anti-oxidant activities and plays an important role in preventing cancer and cardiovascular diseases. In addition, it is potent as the reversal agent of MDR (Multidrug Resistance). As such, it may improve the sensitivity of cancer cells to chemotherapy drugs and reduce toxicity on the heart.

    Production Process

    (1). Picking: Firstly, select high-quality tea trees for picking. Generally speaking, new shoots in spring contain higher levels of EGCG.

    (2). Woqing: Fresh picked tea leaves are treated with Woqing. Woqing refers to killing tea leaves under high temperature and humidity conditions to prevent the activity of enzymes inside the tea leaves and maintain the color and aroma of the tea leaves.

    (3). Rubbing: After the Woqing tea leaves, they need to go through the process of rolling. Rolling can rupture the cell wall of tea leaves, releasing chemicals such as tea polyphenols.

    (4). Fermentation: For some fermented tea leaves (such as oolong tea and black tea), fermentation treatment will be carried out. For green tea, this step will be skipped to maintain the original composition of the tea.

    (5). Drying: Finally, dry the tea leaves to remove moisture and prevent the growth of mold and bacteria.

    (6). Extraction: Dried tea leaves are usually extracted using a solvent (such as ethanol) to dissolve the chemicals in the tea leaves. This step is mainly to extract EGCG from tea leaves.

    (7). Refining: The extracted liquid will be refined to remove impurities and unnecessary components, resulting in higher product purity.

    (8). Crystallization and drying: The refined solution undergoes crystallization and drying, ultimately resulting in the crystallization or powder of EGCG.
