The present study evaluated the antioxidant capacity of the aqueous extract of the leaves of Cynara scolymus on Saccharomyces cerevisiae strains, proficient and deficient in antioxidant defenses, and by in vitro methods with 1,1-diphenyl-2-picrylhydrazyl (DPPH•), 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS•+), inhibition of hydrogen peroxide, lipid peroxidation, formation of nitric oxide, and removal of the hydroxyl radical. A simultaneous quantitative analysis to total phenolics… Expand
