ferric reducing ability of plasma.
This assay measures the antioxidant power of biomolecules via the ability of plasma to reduce Cu2+ to Cu+.
The required hydrogen was generated in situ considering the ability of plasma to decompose methyl radicals to hydrogen.
Hematocrit values increased and the antioxidant index (ferric reducing ability of plasma, FRAP) decreased with a decrease in oxygen saturation levels.
In vitro ferric reducing ability of plasma and 2,2-diphenyl-1-picryl-hydrazyl scavenging assay were not affected by E2 or PG.
In this work, we explore the ability of plasma assisted chemical vapor deposition (PACVD) operating under high power densities to produce thin high-quality diamond layers with a controlled doping with negatively-charged nitrogen-vacancy (NV−) centers.
The following parameters indicative of the oxidative status were measured in plasma: ferric reducing ability of plasma (FRAP), α-tocopherol level, glutathione peroxidase activity (GSH-Px), superoxide dismutase activity (SOD), thiobarbituric acid reactive substances (TBARS) concentration and paraoxonase activity (PON).
The total antioxidant capacity of the IYD ultrafiltered-fractions were measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing ability of plasma (FRAP) assays according to the methods of Brand-Williams et al. (1995) and Amamcharla and Metzger (2014), respectively, and blanks were prepared by adding pH 3.0 PBS in place of the samples.
Total phenolic content, ferric reducing ability of plasma (FRAP) and inhibition of Cu+ 2-induced oxidation of low density lipoprotein (LDL) of the ginger extract were 460 mg gallic acid equivalence (GAE /L, 226 mg Trolox equivalence (TE /L and 43%, respectively.
The present study was designed to measure the antioxidant power of ethanolic extracts of propolis samples from different parts of Iran with "ferric reducing ability of plasma" (FRAP) assay and compare the results with Trolox at concentrations of 100, 1000 and 2000 μg/ml.
The effects of factors (extraction time, irradiation power, number of cycles) and their first order interactions were evaluated from antioxidant activity of extracts using the 2,2′-diphenyl-1-picrylhydrazil (DPPH) free radical scavenging method, the ferric reducing ability of plasma (FRAP) assay, and the estimation of total phenolic content using the Folin Ciocalteu method.
