      Abstract:

        A better characterization of the flavonoids profile and   antioxidant activity of Brazilian cherry fruits is expected to   significantly increase their marketing appeal. Fruits at the   green stage presented the highest antioxidant activity, measured   as DPPHradical dot    scavenging activity (17.18 and 18.13 mmol Trolox equivalents/100   g dried fruits for the red and purple varieties, respectively),   and total phenolic content (4.14 and 5.81 g of ferulic acid   equivalents/100 g dried fruit for the red and purple varieties,   respectively), as well. Use of tandem mass spectrometry allowed   the identification of myricetin 3-O-hexoside, myricetin   3-O-pentoside, myricetin 3-O-rhamnoside, quercetin 3-O-hexoside,   quercetin 3-O-pentoside, quercetin 3-O-rhamnoside, and myricetin   deoxyhexoside-gallate in both varieties of Brazilian cherry,   regardless the developmental stage. Our data indicate that   Brazilian cherry fruits are rich in natural antioxidants that   might be more widely used by both, the general population and the   food industry as a source of bioactive human health promoter   phytochemicals.
