Abstract
Anthocyanins (Acy) in ripening blueberry fruit of the cv. Wolcott were identified and their amounts estimated spectrophotometrically. Fifteen Acy, all combinations of Mv, Pt, Pn, Dp, and Cy with glu, gal, or arab4 in the 3-position were found in unripe, red fruit. Ripe and overripe fruit contained all these Acy except Pn-gal. Cy-glu and Cy-gal comprised about 40% of the total Acy in unripe fruit, while Mv-glu and Mv-gal constituted about 60% in the overripe fruit. The relative proportions of 3-glucosides, 3-galactosides, and 3-arabinosides remained fairly constant throughout fruit ripening.
