Oenin is a type of anthocyanin, a class of compounds with antioxidant effects found naturally in a number of foods. Oenin is responsible for the red and purple colors in grapes and red wine.

Chemical Structure and Properties

Oenin, also known as malvidin 3-glucoside, is a glucoside of malvidin. It has the chemical formula C27H31O15 and a molecular weight of 611.53 g/mol. The compound is soluble in water and has a deep purple color in solution.

Sources and Uses

Oenin is found in high concentrations in the skins of red grapes, particularly Vitis vinifera species.
