Antioxidant activity in acidified by 0.5% HCl methanol extracts (40 mg sample/1 ml extract) was assayed
for scavenging capacity of the DPPH radical (Pekkarinen et al.,1999) and ABTS cation radical (Re et al., 1999). Total polyphenoloxidases activity (PPO) was determined according to Cano et al. (1997), peroxidase (PER) and catalase (CAT) activity according toBergmeyer (1974), monophenolase (MON) and diphenolase (DIP) according toKolcuoglu et al. (2007). Analyses were carried out in four replications for each sample.
