Chemical characterization and antioxidant potential of native fruits of the Cerrado of northern Minas Gerais
Abstract This study aimed to chemically characterize the pulps of the tropical fruits araticum (Annona crassiflora), buriti (Mauritia flexuosa), coquinho azedo (Butia capitata), cagaita (Eugenia dysenterica), and cajá (Spondias mombin), with a focus on antioxidant potential and microminerals.

Zusammenfassung: | Abstract This study aimed to chemically characterize the pulps of the tropical fruits araticum (Annona crassiflora), buriti (Mauritia flexuosa), coquinho azedo (Butia capitata), cagaita (Eugenia dysenterica), and cajá (Spondias mombin), with a focus on antioxidant potential and microminerals. Calcium levels in the Araticum pulp are 9.35 mg/100 g and the iron content was 4.78 mg/100 g. In cagaita pulp, the calcium content was 15.35 mg/100 g and magnesium content was 66.00 mg/100 g. The iron content present in coquinho pulp was 11.47 mg/100 g and in cagaita it was 11.53 mg/100 g. The extracts with the highest contents of total phenolic compounds were araticum (433.80 mg GAE/g) and coquinho (173.5 mg GAE/g). Araticum pulp had the highest antioxidant potential because it had the lowest EC50 (0.04 mg/mL). The results presented here demonstrate the great potential of the fruits of the Cerrado in terms of rich mineral nutrients and bioactive compounds.
Resumo O objetivo deste estudo foi caracterizar quimicamente as polpas das frutas tropicais araticum (Annona crassiflora), buriti (Mauritia flexuosa), coquinho-azedo (Butia capitata), cagaita (Eugenia dysenterica) e cajá (Spondias mombin), com foco no potencial antioxidante e nos microminerais. O nível de cálcio na polpa de Araticum foi de 9,35 mg/100 g e o teor de ferro foi de 4,78 mg/100 g. Na polpa de cagaita, o teor de cálcio foi de 15,35 mg/100 g e o de magnésio, 66,00 mg/100 g. O teor de ferro presente na polpa de coquinho foi de 11,47 mg/100 g e na polpa de cagaita foi de 11,53 mg/100 g. Os extratos com os maiores teores de compostos fenólicos totais foram araticum (433,80 mg GAE/g) e coquinho (173,5 mg GAE/g). A polpa de araticum mostrou o maior potencial antioxidante, pois apresentou a menor EC50 (0,04 mg/mL). Os resultados encontrados demonstram o grande potencial dos frutos do Cerrado em termos de nutrientes minerais ricos e compostos bioativos. |
