Abstract
The aim of this study was to determine the content of bioactive compounds and antioxidant activity present in three fruit species from the Brazilian Cerrado: carnauba (Copernicia prunifera (Mill.) H.E. Moore), murici (Byrsonima crassifolia L. Rich)and oiti (Licania tomentosa (Benth) Fritsch). Among analyzed fruits, oiti showed the highest total phenolic content (1236.42 ± 34.06 mg GAE 100 g-1) followed by murici (468.90 ± 27.30 mg GAE 100 g-1) and carnauba (314.44 ± 9.50 mg GAE 100 g-1). Regarding the antioxidant activity, murici showed 4350.31 ± 1.85 µmol TEAC.100 g-1 and oiti showed 14721.69 ± 0.85 µmol TEAC.100 g-1. In addition, high content of anthocyanins was verified in carnauba (9.35 ± 0.00 mg-cy-3-glu.100 g-1), as well as carotenoids (20.0 ± 1.23 mg-ß-carot.100 g-1) and vitamin C (58.60 ± 1.32 mg.100 g-1) in murici. In conclusion, data obtained add valuable information to the current knowledge on the nutritional and functional features of fruits from the Brazilian Cerrado that have been scarcely explored, such as those analyzed, which showed high content of bioactive compounds and antioxidant activity.
