Ascorbic acid and phenolic contents, antioxidant capacity and flavonoids composition of Brazilian Savannah native fruits

Abstract Brazilian Savannah native fruits have been investigated as potential sources of antioxidant substances. Cagaita, cerrado cashew and gabiroba were characterized with regard to the ascorbic acid and phenolic contents, antioxidant capacity and flavonoids composition. Gabiroba presented higher contents of ascorbic acid (61.5 mg.100 g–1), total phenolic compounds (1,222.59 mg GAE.100 g–1), and antioxidant capacity (DPPH, FRAP and ORAC assays) than cagaita and cerrado cashew. The correlation coefficients between total ascorbic acid or total phenolic contents and antioxidant capacity wer...
