Pollen from Stryphnodendron polyphyllum, known as barbatimão, is a problem for beekeepers who have apiaries close to the plant, due to toxicity for bees. The objective was to evaluate the antioxidant, antibacterial activity and determine total phenols and tannins in ethanolic extract. Antioxidant activity was evaluated by DPPH method. Antibacterial activity was performed by microdilution method. Total tannins and phenols were determined by spectrophotometric method. We had results inhibitory and bactericidal activity for E. coli, P. aeruginosa, S. mutans, S. sobrinus, S. sanguinis, S. salivarius and L. paracasei. EC50 of 7.42mg/mL was determined in the antioxidant activity. For phenolic and tannic compounds, the results, by comparison of calibration curve, were 3.12±0.005g/100g expressed as gallic acid and 7.3±0.03g/100g expressed as tannic acid. High performance liquid chromatography was performed to obtain the chromatographic profile. [ABSTRACT FROM AUTHOR]
