Background: Brazil is considered a country with the highest biological biodiversity in
the world and exploring underutilized food sources could diversify food production and reduce nutritional
Objective: This study aimed to determine the antioxidant capacity and the bioactive compounds of
seven native fruits from Brazil.
Methods: The samples were obtained from different cities of Brazil after confirmation of the botanical
species. Carotenoids and anthocyanins were exhaustively extracted and injected into high-performance
liquid chromatography. The antioxidant capacity was determined by assessing the free
radical ABTS. Vitamin A activity was calculated based on retinol activity equivalent. Complex B
and C vitamins were determined by high-performance liquid chromatography.
Results: The main carotenoid for all species was β-carotene, and Jaracatiá showed the highest
amount of β-cryptoxanthin, zeaxanthin, α- and β-carotene. Açaí Juçara and the Butiás stood out
among fruits analyzed with the highest antioxidant capacity (trolox equivalent). Concerning anthocyanins
in Açaí Juçara, compounds Cyanidin 3-glucoside and Cyanidin 3-rutinoside were identified.
The values of all the compounds vary according to the harvest location. Jaracatiá is distinguished
by the high vitamin A, C, B2, and B6 content, as well the Butiás (Praia and Serra), for B1,
B2, B5 and B7. Vitamin B3 was only detected in Fisális fruits and Açaí showed higher content of
Conclusion: Fruits included in this study were found to have considerable amounts of bioactive
compounds, vitamins and antioxidant capacity, showing that they can contribute to the improvement
of diet of the population.
