Antioxidant and radical scavenging properties of curcumin.
Tuba Ak,İlhami Gülçin +1 more
TL;DR: The antioxidant activity of curcumin was determined by employing various in vitro antioxidant assays such as 1,1-diphenyl-2-picryl-hydrazyl free radical (DPPH*) scavenging, 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radical scavenging activity, N,N-dimethyl-p-phenylenediamine dihydrochloride

Antioxidant properties of resveratrol: A structure–activity insight
TL;DR: In this paper, the antioxidant activity of resveratrol was investigated by employing various in vitro assays such as DPPH•, ABTS•, DMPD•+, O2•− and H2O2 scavenging activities, total antioxidant activity, reducing abilities, and Fe2+ chelating activities.
Journal ArticleDOI
Antioxidants and antioxidant methods: an updated overview
TL;DR: Antioxidants had a growing interest owing to their protective roles in food and pharmaceutical products against oxidative deterioration and in the body and against oxidative stress-mediated pathological processes as discussed by the authors, and many studies evaluating the antioxidant activity of various samples of research interest have been conducted.
