Abstract : Native to Atlantic Forest, found from south Bahia to the north of Rio Grande do Sul, the juçara palm (Euterpe edulis Mart.) has great ecological and economic importance to Brazil, especially in the states of Santa Catarina, Paraná and São Paulo. The continuous and disorderly exploitation for palm heart production resulted in near extinction of the species, since palm heart extraction involves the sacrifice of the plant. Recently, more attention has been given to the exploitation of juçara fruits, very similar to the fruits grown in Amazon (Euterpe oleracea species) and used for the production of açaí. The juçara fruits are rounded, when ripe are violet-purple color, and its use to obtain pulp has become a way of reconciling environmental protection of the species with added economic value. This study aimed to evaluate the mineral content and its bioaccessibility and the profile of phenolic compounds in juçara fruit collected in Florianópolis/SC at different ripening stages. Minerals and their bioaccessibility, and the content of phenolic compounds showed changes during advancing maturity. The application of the in vitro bioaccessibility methodology showed that the fruits harvested at the end of ripening stages (sixth and seventh) showed a better mineral content, especially Mn, Se, Cu, Ca and Fe. With the use of HPLC-ESI-MS / MS were identified phenolic acids (protocatechuic, gallic and ?-coumaric acid), flavonoids (kaempferol, aromadendrin, hispidulin, quercetin, taxifolin, myricetin and rutin) and stilbene (resveratrol). The phenolic acids and flavonoids shown the highest concentrations, mostly in fruits collected until the third ripening stage, with the exception of rutin and quercetin, which showed the highest levels at the end of the ripening cycle. The results of this study show that the consumption of juçara fruit can significantly contribute to the recommended daily intake of minerals and maximize dietary intake of antioxidant compounds, which can benefit the consumer health.
