Abstract
This work evaluated the bioactive compounds and the antioxidant potential of honey produced by Africanized bees (Apis mellifera L.) in the state of Piauí, Brazil. The analyses show that all honeys investigatedpresented features of the pollen type Mimosa caesalpiniifolia. The content of phenolic compounds ranged from 27.65 to 97.01 mg in GAE g-1 of honey, with an average content of 62.66 ± 20.46 mgEAG g-1 of honey. The total flavonoid contents expressed in mg of quercentin/g of honey ranged from 5.43 to 13.02 mg of QE g-1, with an average of 8.33 ± 1.86 mg of QE g-1 of honey. The best performance of antioxidant activity by reducing power was EC50 of 0.15 and the lowest performance of antioxidant activity with IC50 was 1.24. The highest antioxidant activity (DPPH) ranged from 66.11 ± 0.02mg EAQ 100g-1, while the lowest activities were 9.16 and 10.88 mg EAQ 100g-1. The results show that the contents of total phenolic compounds, total flavonoids, DPPH antioxidant activity, and the pollen-reducing power from Piauí were influenced by botanical origin.

Summary
Compostos bioativos e potencial antioxidante do mel produzido por abelhas africanizadas (Apis mellifera L.) no Piauí. O objetivo deste trabalho foi avaliar os compostos bioativos e o potencial antioxidante do mel produzido por abelhas africanizadas (Apis mellifera L.) do Piauí. O teor dos compostos fenólicos variaram de 27,65 a 97,01 mg em GAE g-1 de mel, com um teor médio de 62,66 ± 20,46 mgEAG g-1 de mel. Enquanto os teores de flavonoides totais expressos em mg quercentina/g de mel variaram de 5,43 a 13,02 mg QE g-1, com média de 8,33 ± 1,86 mg QE g-1 de mel. Diante dos resultados obtidos nas análises, constatou-se que o teor de compostos fenólicos totais, flavonoides totais, atividade antioxidante de DPPH e pelo poder redutor do pólen oriundo do Piauí, sofreram influência quanto à origem botânica.
