Abstract: The Cerrado is one of the world's biodiversity hotspots and Brazil’s second largest biome. Many native species of the Brazilian Cerrado provide fruits that have unique sensory characteristics and high nutritional value. This study aimed at characterizing the pulp of Eugenia klotzschiana O. Berg, concerning its proximal composition, bioactive compound content and antioxidant activity. The pulp under study had high moisture (89.47 g kg-1) and caloric (96.07 kcal kg-1) values whereas its contents of protein (0.59 g kg-1) and lipids (2.35 g kg-1) were low. The cerrado pear pulp also had high iron content (16.5 mg kg -1) and dietary fiber (6.45 g kg-1), besides 0.034-0,055 mg kg-1 carotenoids, 8.66 mg kg-1 ascorbic acid and 0.66 mg kg-1 total chlorophyll. Total phenolic compounds (333.41-566.33 mg EAG kg-1) and flavonoids (225-50 mg EQ kg-1) were found by extraction methods named Method 1 (water) and Method 2 (acetone+methanol), respectively. Thus, the cerrado pear can be an alternative to improving nutrient intake and to providing sustainable use of the native flora in the Cerrado.
