Abstract:
Samples of fruit from the jussara palm plant (Euterpe edulis), collected in different regions of the state of Santa Catarina, Brazil, were analyzed for chemical composition, phenolic acids, anthocyanins, flavonoids and fatty acids profile. Results indicated that the jussara fruit has a high lipid content (18.45–44.08%), oleic acid (44.17–55.61%) and linoleic acid (18.19–25.36%) are the fatty acids found in the highest proportion, and other components were proteins (5.13–8.21%), ash (1.55–3.32%) and moisture (34.95–42.47%). Significant differences were found in the total phenolic, total monomeric anthocyanins and other flavonoids for the samples from the five cultivation regions. The fruit from region E harvested in summer, with high temperatures and medium altitudes, had the highest contents of total phenolics (2610.86±3.89mg 100g⁻¹ GAE) and monomeric anthocyanins (1080.54±2.33mg 100g⁻¹ cy-3-glu). The phenolic compound included ferulic, gallic, hydroxybenzoic and p-coumaric acids, as well as catechin, epicatechin and quercetin. The results show promising perspectives for the exploitation of this tropical fruit with a chemical composition comprising considerable phenolic acids and flavonoids compounds and showing activity antioxidant.
