Thiols as major determinants of the total antioxidant capacity

BioFactors, 2003
The proper functioning of aerobic organisms subjected to the danger of uncontrolled oxidation depends critically on the efficient antioxidant system. This system includes antioxidant enzymes, low-molecular weight antioxidants and biological chelators of transition metal ions. What is an antioxidant?

Rapid measurement of total antioxidant capacity in plants

Nature Protocols, 2007
There is growing interest in measuring the antioxidant status of plant tissues. This protocol describes the oxygen radical absorbance capacity (ORAC) assay, which measures antioxidant inhibition of peroxyl radical-induced oxidations and is a measure of total antioxidant capacity.

The association of total antioxidant capacity with sex hormones

Scandinavian Cardiovascular Journal, 2005
Although sex hormones have potential cardioprotective effects, their effects on total antioxidant capacity (TAC) are not very well known. The aim of the study was to evaluate TAC in men who have decreased and normal testosterone levels and in women in menopausal and premenopausal period.Ninety-seven subjects with similar age intervals, men aged

Renal regulation of plasma total antioxidant capacity

Medical Hypotheses, 2001
Hyperuricemia has been labeled both a risk factor and marker for cardiovascular pathology in addition to being associated with gout and kidney disease. Uric acid in vitro acts as a potent antioxidant capable of scavenging hydroxy radicals and peroxynitrite and reacting with nitric oxide.

Chemiluminescent determination of total antioxidant capacity during winemaking

Luminescence, 2006
AbstractThe total antioxidant capacity (TAC) of five different wines (four red and one white) was determined in five different steps of winemaking carried out in a commercial wine cellar by a chemiluminescence (CL) assay. The CL method is suitable to determine the antioxidant capacity of beverages, and preliminary trials showed that the TAC immediately

Total Antioxidant Capacity of Teas by the Ferric Reducing/Antioxidant Power Assay

Journal of Agricultural and Food Chemistry, 1999
This study aimed to compare in vitro antioxidant power of different types of tea (Camellia sinensis). The ferric reducing/antioxidant power (FRAP) assay was used to measure the total antioxidant power of freshly prepared infusions of 25 types of teas.

Effect of fruit and vegetable antioxidants on total antioxidant capacity of blood plasma

Nutrition, 2014
For a long time, the increased consumption of fruits and vegetables was considered critical in protecting humans against a number of diseases, such as cancer, diabetes, neurodegenerative diseases, and heart and brain vascular diseases. Presently, it is thought that the protective properties of these foods result from the presence of low-molecular ...

Depletion of total antioxidant capacity in type 2 diabetes

Metabolism, 1999
The purpose of the study was to examine the relationship between antioxidant depletion, glycemic control, and development of chronic complications in a controlled population of type 2 diabetic patients. Fifty age-matched type 2 diabetic patients receiving sulfonylureas but not insulin treatment were screened and assigned to two groups based on the ...

Contribution of Anthocyanin Composition to Total Antioxidant Capacity of Berries

Plant Foods for Human Nutrition, 2015
The present study aimed to evaluate the contribution of anthocyanin composition to the total antioxidant capacity (TAC) of berries having different anthocyanin composition; blackberry, black currant, and blueberry. Blackberry demonstrated the highest TAC, while it had the lowest total anthocyanin content among the three berries in both of the phenolic ...

Direct measurement of the total antioxidant capacity of cereal products

Journal of Cereal Science, 2008
Abstract A simple and rapid procedure was developed for the direct measurement of the antioxidant capacity of cereals. It entails grinding of cereals, mixing with 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) reagent, centrifugation and measure of the absorbance. The ABTS reagent was dissolved in a mixture of ethanol:water (50:50, v/v),
