Abstract : Mango (Mangifera indica L.) is one of the most important tropical fruits and its pulp is known to be a rich source of carotenoids. Investigations on the phenolic composition of the peels of a red-colored cultivar (cv. 'Tommy Atkins') revealed the presence of a new anthocyanin, 7-O-methylcyanidin 3-O-?-D-galactopyranoside. Its structure was elucidated by extensive 1D and 2D NMR studies, MS, and chemical transformation.
