Correlation between the Antiradical Activity (ARA) and Total Phenolic Content for each raw species (A-E). A Reichardia picroides (◆) y = 0.047x +0.25; R2 = 0.92; B Hypochaeris radicata (■) y = 0.031x +0.009; R2 = 0.93; C Cichorium intybus () y = 0.011x +0.34; R2 = 0.52; D Tordylium apulum (x) y = 0.004x +0.45; R2 = 0.33; and E Helminthotheca echioides (•) y = 0.03x+0.25; R2 = 0.45. A (p< 0.05), B (p< 0.05), C (p< 0.1), D (p< 0.3), and E (p< 0.1). Linear regressions and best fit values were calculated using the Grahpad Prism 4 program (http://www.graphad.com).
