Brazil is recognized for its vast biodiversity, home to biomes such as the Cerrado, where the mangaba (Hancornia speciosa) is found, a fruit with high nutritional and medicinal potential. This study aimed to evaluate the mineral content and antioxidant activity of mangaba fruits collected in the Cerrado Goiano. The fruits were processed and analyzed for their mineral content (N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn, B), carotenoids (β-carotene and lycopene), phenolic compounds, and antioxidant capacity using the DPPH method. The results showed a high concentration of nitrogen, sulfur, and potassium, essential for the development of the fruit and beneficial for human health. In addition, relevant amounts of iron and magnesium were identified, which reinforces their nutritional value. Regarding bioactive compounds, 34.00 mg/100 g of β-carotene, 3.00mg/100 g of lycopene, and 40.00 mg/g of DPPH were found, indicating a significant antioxidant capacity, although lower than other fruits of the Cerrado. The phenolic content was also higher than that reported in other studies, which can be attributed to environmental and methodological factors. The results show that mangaba is a rich source of minerals and antioxidant compounds, with potential for applications in the food and pharmaceutical industry. Its use can contribute to the development of natural functional products, promoting the valorization of native species of the Cerrado.
