Activity of catechins and their applications

Abstract

Background: Catechins, which are polyphenol compounds found in many plants and are an important component of tea leaves, are strong anti-oxidants. Research: Many studies seek to enhance the effects of catechins on the human body and boost their protective power against UV radiation. There are many examples of the positive anti-microbial, anti-viral, anti-inflammatory, anti-allergenic, and anti-cancer effects of catechins. Catechins increase the penetration and absorption of healthy functional foods and bio cosmetics into the body and the skin, thus improving their utility. High value-added antioxidant substances have been extracted from food and plant sludge, and experiments have shown that catechins are safe when applied to the human body. The stability of catechins is very important for their absorption into the human body and the effectiveness of their anti-oxidant properties.Conclusion: Continued research on the strong anti-oxidant effects of catechins is expected to result in many advances in the food, cosmetics, and pharmaceutical industries.

Curative Effect of Catechin Isolated from Elaeagnus Umbellata Thunb. Berries for Diabetes and Related Complications in Streptozotocin-Induced Diabetic Rats Model

“…These results were in line with other previous studies where it has been observed that increase in circulating free fatty acids enhances hepatic TGs production. High TGs content associated with formation of an atherogenic dyslipidaemia consisting of an elevation in high TG content, low HDL cholesterol and increased LDL or apo lipoprotein-B [ 19 , 30 ]. Epidemiological studies indicated that regular intake of more than two cups of green tea and its catechin have been shown to ameliorate oxidative stress, hyperlipidemia and lower the concentration of TC and LDL, which has also been demonstrated in the performed meta-analysis of randomized clinical trials [ 31 ].…”

“…Flavonoids are the most potent antioxidant identified in significant amounts in fruit and vegetable. Catechin is one of the most important flavonoids, with a comparatively high antioxidant activity [ 19 ]. Catechins have the beneficial effect of preventing skin damage.…”

“…The major sources of catechin are Camellia sinensis ( C. sinensis ) and C. assumica. Green tea contains 75–80% water and polyphenol (flavanols, flavandiols, flavonoid, and phenolic acid) compounds [ 19 ]. Green tea is a popular beverage consumed worldwide for its long history and numerous health benefits due to the presence of various amounts of catechins such as catechin, (–)-epigallocatechin-3-gallate, (–)-epicatechin-3-gallate, (–)-epigallocatechin, and (–)-epicatechin.…”

“…Catechins are one of the most important flavonoids, with antioxidant and anti-inflammatory properties rendering them a potent therapeutic for diseases where the mentioned processes are critical negative elements [ 20 ]. A number of scientists have isolated catechin from different plants and evaluated them to be beneficial in controlling oxidative stress, diabetes, high blood pressure, lipid absorption and glucose intolerance induced by a high fat diet [ 19 , 21 , 22 ].…”
