Anthoxanthines
Anthoxanthines are water-soluble flavonoid pigments in plants. It is light to dark yellow plant pigments consisting of glycosides that are found in roots, leaves and flowers of many plant species. In acidic environments they are usually whiter and in alkaline media they are more yellow. Like anthocyanins, anthoxanthines are very susceptible to color changes in the presence of minerals and metal ions and darken significantly when heated. Like all flavonoids, they have antioxidant properties, are important in nutrition, and are sometimes used as food additives. Examples of anthoxanthines are quercetin , eriodictin , hesperidin , naringin and others. The related sugar-free coloring agents are called anthoxanthidines .
