Phenolic compounds determination was performed using the Folin-Ciocalteu method (SINGLETON; Rossi and Singleton, 1965;Peschel et al., 2006). The reaction mixture was composed by 0.1 mL of extract (1667 mg/L), 7.9 mL of distilled water, 0.5 mL of Folin-Ciocalteau reagent (a mixture of phosphomolybdate and phosphotungstate) and 1.5 mL of 20% sodium carbonate.
