Abstract
The concentration of bioactive compounds and antioxidant activity of pollen may vary depending on the botanical origin. Thirty-three samples of bee pollen from the region of Alagoinhas-BA were investigated on the concentrations of phenolic compounds, flavonoids, carotenoids and antioxidant activity, and the correlation between bioactive compounds and Eucalyptus and Mimosa pudica pollens was assessed. The phenolic compounds contents and of its flavonoid fraction in samples with the occurrence of Mimosa pudica ranged from 14.31 to 64.14 mg in GAE.g-1 of pollen and from 0.72 to 1.99 mg, respectively; the samples with the occurrence of Eucalyptus ranged from 26.48 to 132.38 mg GAE.g-1 of pollen and from 1.55 to 2.5 mg, respectively. The carotenoids contents ranged from 18.16 to 764.37 μg.g-1 in Mimosa pudica pollen type, and from 3.01 to 46.08 μg.g-1 in Eucalyptus pollen type. The antioxidant activity ranged from 37.94 to 91.81% and from 78.96 to 93.21% in samples with occurrence of Eucalyptus and Mimosa pudica pollen types, respectively. A positive correlation between the Eucalyptus pollen type and the phenolic compounds contents was found, however no statistically significant correlation was observed between the Mimosa pudica pollen type and carotenoids contents.
