Characterization of antioxidant activities from fruits rich in delphinidin or malvidin anthocyanins
… many chronic diseases . Although the antioxidant capacity of anthocyanins has been well established, less is known about the extent to which specific anthocyanin composition affects total antioxidant capacity . The aim of the present study was to compare the antioxidant capacity of two different …

Honey as a Source of Natural Antioxidants
… antioxidant activity of honey as measured by the oxygen radical absorbance capacity (ORAC) assay, was found to be similar to the antioxidant activity of many fruits and vegetables on a fresh weight basis. The ORAC values of honeys from various floral sources were significantly correlated with the …

A comparative study of white, black and green tea solutions as potential antiviral agents in rhesus monkey kidney cells induced with porcine rotavirus
… Antioxidant capacities were determined using the oxygen radical absorbance capacity (ORAC) assay. The values of antioxidant capacity for all teas ranged from (31.6 ± 0.71 to 46.8 ± 0.14 mM Trolox equivalents/ml); Green Tea had the highest antioxidant capacity when compared to other teas. Analysis …

Genomic and biochemical investigation of soybean antioxidant metabolism in response to growth at elevated carbon dioxide and elevated ozone
Metabolism in an environment containing of 21% oxygen has a high risk of oxidative damage due to the formation of reactive oxygen species. Therefore, plants have evolved an antioxidant system consisting of metabolites and enzymes that either directly scavenge ROS or recycle the antioxidant …
