متن کاملExtending applicability of the oxygen radical absorbance capacity (ORAC-fluorescein) assay.
The ORAC-fluorescein (ORAC-FL) method recently validated using automatic liquid handling systems has now been adapted to manual handling and using a conventional fluorescence microplate reader. As calculated for Trolox, the precision of the method was <3.0, expressed as percent coefficient of variation. The accuracy of the method was <2.3, expressed as percent variation of the mean. The detecti...
متن کاملPerforming Oxygen Radical Absorbance Capacity Assays with SynergyTMHT
Introduction The antioxidant capabilities of foods, cosmetics, supplements and pharmaceutical agents has become of particular interest. This is the result of the evidence demonstrating the relationship of reactive oxygen/nitrogen species (ROS) with aging and pathogenesis. [1,2]. Living organisms: use of a fuel (ATP) whose production results in the formation of toxic compounds, and requires that...
متن کاملEvaluation of Oxygen Radical Absorbance Capacity in Kampo Medicine
Antioxidant capacity of food has come to be shown in terms of oxygen radical absorbance capacity (ORAC) mainly on vegetables or fruit. However, the evaluation of Kampo in terms of ORAC has not yet been accomplished. It is important that such an investigation is also conducted for Kampo medicine. We measured the ORAC value of almost all the available Kampo formulas used in the Japanese National ...
متن کاملInfluence of finishing systems on hydrophilic and lipophilic oxygen radical absorbance capacity (ORAC) in beef.
The aim of this research was to: (1) develop a reliable extraction procedure and assay to determine antioxidant activity in meat products, and (2) assess the effect of beef finishing system (forage-finished: alfalfa, pearl millet or mixed pastures vs. concentrate-finished) on longissimus muscle antioxidant activity. The effect of extraction method (ethanol concentration and extraction time), pr...
