Phenolic structures comprise a diverse group of molecules classified as secondary metabolites in plants that have a large range of structures and functions. Taxifolin is effective polyphenolic compounds and a food and nutritional supplements. A greater number of potential clinical applications have been reported. Taxifolin was found to be a powerful antioxidant and antiradical activities in different in vitro bioassays when compared with standard antioxidant compounds. As discussed above, taxifolin can be used for minimizing or preventing lipid oxidation in food or pharmaceutical products, delaying the formation of toxic oxidation products, maintaining nutritional quality, and prolonging the shelf life of food or pharmaceutical materials.
