Evaluation of Antioxidant Capacity of Cereal Brans
Journal of Agricultural and Food Chemistry, 2004Several oat brans (crunchy oat bran, oat bran alone, and oat breakfast cereal) and wheat brans (wheat bran alone, wheat bran powder, wheat bran with malt flavor, bran breakfast cereal, tablet of bran, and tablet of bran with cellulose) used as dietary fiber supplements by consumers were evaluated as alternative antioxidant sources (i) in the normal ...

Albumin antioxidant capacity is modified by methylglyoxal
Diabetes & Metabolism, 2005Oxidative stress seems to play a major role in diabetic vascular complication development. Plasma albumin, via its thiol groups, is the main extracellular antioxidant molecule. Methylglyoxal (MG) is a very reactive dicarbonyl compound increased in diabetes which strongly modifies proteins by non-enzymatic glycosylation.

Electroanalysis, 2008
AbstractThe CRAC assay is a direct electron transfer test of antioxidant capacity for several organic compounds. The ability of eight different compounds in reducing Ce4+ was studied by chronoamperometric measurements of the remaining Ce3+ species. The following antioxidant classification was observed: tannic acid $\rm{ \gg }$ quercetin>rutin> ...

The Chemistry behind Antioxidant Capacity Assays
Journal of Agricultural and Food Chemistry, 2005This review summarizes the multifaceted aspects of antioxidants and the basic kinetic models of inhibited autoxidation and analyzes the chemical principles of antioxidant capacity assays. Depending upon the reactions involved, these assays can roughly be classified into two types: assays based on hydrogen atom transfer (HAT) reactions and assays based ...

Chemical Product and Process Modeling, 2013
Abstract Inconsistent ranking is a well-known drawback of antioxidant capacity (AOC) profiling methodologies that use free-radical species as oxidant. This problem leads to assay results that are not biorelevant. Linear free energy relationships (LFER) theory predicts proton transfer (PT) kinetics as a surrogate for biorelevant ...

Assessment of the kinetics of the antioxidative capacity of topical antioxidants.
Journal of drugs in dermatology : JDD, 2011While there is at least one standardized test available for evaluating the antioxidant capacity of cosmetic formulations, the authors proposed a new in vivo method to determine kinetics of squalene (SQ) photo-oxidation products (squalene monohydroperoxide, SQmOOH) as a reliable method with which to evaluate antioxidant capacity of a cosmetic ...

Assessment of Antioxidant Capacity of Natural Products
Current Pharmaceutical Biotechnology, 2010It is now widely accepted that oxidative stress induced by reactive oxygen and nitrogen species is involved in the pathogenesis of various diseases such as atherosclerosis and cardiovascular disease and consequently the role of antioxidants in the prevention and treatment of diseases has received much attention of scientists, clinicians and general ...

Phenolic Compounds of Cereals and Their Antioxidant Capacity
Critical Reviews in Food Science and Nutrition, 2014Phenolic compounds play an important role in health benefits because of their highly antioxidant capacity. In this review, total phenolic contents (TPCs), phenolic acid profile and antioxidant capacity of the extracted from wheat, corn, rice, barley, sorghum, rye, oat, and millet, which have been recently reported, are summarized.
