Values are the mean of three replicates (mean (% dw) ± s.d.). s.d., standard deviation. sc-CO2, supercritical carbon dioxide, BHA, butylated hydroxyanisole, EC50 refers to the quantity of extract required to reduce DPPH radical by 50%. a-c, letters in the same column represent significant differences according to Tukey’s pairwise a posteriori test, considering p < 0.05. α-γ, letters in the same row represent significant differences according to Tukey’s pairwise a posteriori test, considering p < 0.05.
