Anthocyanidins, also known as flower pigments, are colored aglycones derived from the hydrolysis of anthocyanins. They are a class of water-soluble natural pigments found widely in plants. Blueberries and mulberries are common natural sources of anthocyanidins. Anthocyanidins are primarily used for food coloring, but are also used in dyes, pharmaceuticals, and cosmetics.
