Values with a different letter (a–c) within a column of the same extraction solvent are significantly different (); values with a different letter (A–C) within a row of the antioxidant activity are significantly different (); ± standard deviation of three replicates. HEX: hexane; ACTN: acetone; ACN: acetonitrile.
