Catechin and its Derivatives
Özet
Catechins are flavanols found in wine, tea, fruit, and chocolate. Catechins are divided into subgroups such as gallocatechin, epicatechin, epigallocatechin gallate, epicatechin gallate, gallocatechin gallate, and catechin gallate. Catechins possess strong antioxidant activity and are used in electrical, viral, fungal, bacterial, gastrointestinal, cancer, and surgical treatments. The antioxidant potential of catechins increases in the order EKG>EGKG>EGK>EK. Catechins occupy an important place among the components of tea and constitute approximately one-third of the dry weight of tea. With the recent widespread increase in their antioxidant properties, the importance of catechins, especially in green tea, is quite significant due to their appearance as antioxidants. Many studies have shown that catechins, belonging to the polyphenol group, are found in high amounts in green tea and possess anticancer, antimutagenic, antioxidant, and hypolipidemic effects. Catechins are known to increase antioxidant enzymes and eliminate reactive oxygen species such as superoxide, hydroxy, and peroxyl radicals. Catechins and other active compounds obtained from green tea have the ability to repair DNA damage caused by exposure to UV-B radiation. Catechins are particularly effective in this regard. Current data show that the active compounds in green tea have a high level of efficiency in protecting the skin from the harmful effects of UV radiation. Catechins offer numerous health benefits by effectively eliminating free radicals and slowing down the breakdown of the extracellular matrix caused by exposure to ultraviolet (UV) radiation and pollution. Catechins are used in many pharmacological formulations.
