Flavonoid - an overview ScienceDirect Topics

WebFlavonoids are a large group of plant chemicals naturally found in many foods. They’re sometimes also called bioflavonoids or polyphenols . Flavonoids were discovered in 1930 when a new... Flavonoids are secondary metabolites synthesized mainly by plants. The general structure of flavonoids is a 15-carbon skeleton, containing 2 benzene rings connected by a 3-carbon linking chain. Therefore, they are depicted as C6-C3-C6 compounds. Depending on the chemical structure, degree of oxidation, and … See more Flavonoids (or bioflavonoids; from the Latin word flavus, meaning yellow, their color in nature) are a class of polyphenolic secondary metabolites found in plants, and thus commonly consumed in the diets of humans. See more In the 1930s, Albert Szent-Györgyi and other scientists discovered that Vitamin C alone was not as effective at preventing scurvy as the crude yellow extract from oranges, lemons or paprika.
