Polysaccharide-based nanoparticles by chitosan and gum arabic polyelectrolyte complexation as carriers for curcumin
TL;DR: In this article, the polysaccharide-based nanoparticles by the polyelectrolyte complexation between chitosan (CS) and gum arabic (GA) were developed as novel delivery systems for curcumin.
Journal ArticleDOI
Lycopene and Its Antioxidant Role in the Prevention of Cardiovascular Diseases-A Critical Review.
TL;DR: Most studies showed beneficial effects of lycopene to individuals who are antioxidant-deficient like elderly patients, or humans exposed to higher levels of oxidative stress like smokers, diabetics, hemodialysis patients and acute myocardial infarction patients.
Journal ArticleDOI
Liposome as a delivery system for carotenoids: comparative antioxidant activity of carotenoids as measured by ferric reducing antioxidant power, DPPH assay and lipid peroxidation.
TL;DR: In this paper, the carotenoids exerted antioxidant activity after encapsulation in a liposome delivery system, for food application, and three assays were selected to achieve a wide range of technical principles, including 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging, ferric reducing antioxidant powder (FRAP), and lipid peroxidation inhibition capacity (LPIC) during lipid preparation, auto-oxidation, or induced by ferric iron/ascorbate.

The ferric reducing ability of plasma (FRAP) as a measure of 'antioxidant power' : the FRAP assay
TL;DR: The FRAP assay offers a putative index of antioxidant, or reducing, potential of biological fluids within the technological reach of every laboratory and researcher interested in oxidative stress and its effects.
Journal ArticleDOI
The Chemistry behind Antioxidant Capacity Assays
TL;DR: This analysis suggests that the total phenols assay by FCR be used to quantify an antioxidant's reducing capacity and the ORAC assay to quantify peroxyl radical scavenging capacity, to comprehensively study different aspects of antioxidants.
