Figure 2: Hydrophilic (a), lipophilic (b), and total (c) antioxidant activity evaluated by the TEAC assay in different chicory varieties and wild poppy plants collected in Salento. Values are expressed as μmol Trolox equivalent (T.E.)/100 g f.w. and represent the mean ± standard deviation of three independent replicates (). Data were submitted to one-way analysis of variance (ANOVA), and bars marked with different letters indicate significant differences among samples (Holm-Sidak post hoc test, ).
