Rapid measurement of total antioxidant capacity in plants
Nature Protocols, 2007There 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, 2005Although 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

Total plasma antioxidant capacity in cystic fibrosis
Pediatric Pulmonology, 2000Several studies have demonstrated ongoing oxidative stress in cystic fibrosis (CF). With the complexity of the antioxidant network, measurement of individual antioxidants does not necessarily assess how they work in combination. One measure that has been proposed as a gauge of total plasma antioxidant capacity is the Trolox-equivalent antioxidant ...

Renal regulation of plasma total antioxidant capacity
Medical Hypotheses, 2001Hyperuricemia 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, 2006AbstractThe 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, 1999This 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, 2014For 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, 1999The 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, 2015The 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 ...
