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

Chemicals Compositions, Antioxidant and Anti-Inflammatory Activity of Cynara scolymus Leaves Extracts, and Analysis of Major Bioactive Polyphenols by HPLC
TLDR
EtOH extract of ALE contained the highest phenolic, flavonoid, and tannin contents and the strongest antioxidants activities and exhibited a maximum inhibition of inflammation induced by Carr for 3 and 5 hours compared to reference group Indomethacin (Indo). Expand
Spectroscopic studies on the in vitro antioxidant capacity of isopentyl ferulate.
TLDR
It is demonstrated that isopentyl ferulate has an antioxidant activity in vitro experimental models, suggesting that this compound could enhance the development of a new product with antioxidant properties, however, further in vivo studies are needed to assign possible implications in the treatment of diseases related with free radicals.
