Flavonoids are natural antioxidants

Abstract

Studies have shown that flavonoids are phenolic compounds that are widely synthesized in most plants. However, the antioxidant activities of flavonoids attract more attention. Oxidative damage is one of the main causes of premature aging and a number of diseases (such as cardiovascular disease and cancer). Consumption of foods rich in flavonoids is important in the prevention of such diseases. This protective effect of fruits and vegetables depends on the flavonoids which they contain. A number of plant extracts were obtained, the flavonoid content was studied and the results were reflected in the article. The spectra of the extracts were taken using a Hitachi U-2900 UV-VIS spectrophotometer, the flavonoid content was determined and an important flavonoid compound quercetin was detected.
