The efficacy of anthocyanins
Anthocyanin is a kind of water-soluble natural pigment widely existing in plants.
Anthocyanins are derivatives of glycosides. Procyanidins are bioflavonoid compounds with special molecular structure. Procyanidins can be converted into anthocyanins in plants.
Anthocyanins are water-soluble pigments that change color with the acid and base of the cell fluid. Anthocyanins are found only in blueberry fruits, purple potatoes, and grape skins.
