Gao, L. | Mazza, G.
The anthocyanins and colorless phenolics in 11 cultivars and hybrids of sweet cherries were characterized and quantified by high-performance liquid chromatography and gas chromatography. All of the dark-colored cherry genotypes were found to contain 3-rutinoside and 3-glucoside of cyanidin as the major anthocyanins and the same glycosides of peonidin as minor anthocyanins. Another minor anthocyanin, pelargonidin 3-rutinoside, was characterized in sweet cherries for the first time. The major colorless phenolics were characterized as neochlorogenic acid and p-coumaroylquinic acid. The total anthocyanin content ranged from 82 to 297 mg/100 g of pitted cherry for the dark cherries and from 2 to 41 mg/100 g of pitted fruit for the light-colored cherries. The neochlorogenic acid ranged from 24 to 128 mg/100 g of pitted cherry and p-coumaroylquinic acid from 23 to 131 mg/100 g, respectively. The relative amounts of the two phenolic acids varied widely across the cherry cultivars examined in this study.
