Figure 3: Total phenols (a) and flavonoids (b) in different chicory varieties and wild poppy plants collected in Salento. Total phenol values are expressed as mg gallic acid equivalent (G.A.E.)/100 g f.w.; flavonoid values are expressed as mg catechin equivalent (C.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); bars marked with different letters indicate significant differences among samples (Holm-Sidak post hoc test, ).
