(2013)A novel ORAC (oxygen radical absorbance capacity) assay to assess antioxidant capacity of phenolic compounds in near-gastric conditions (pH 2.0) is presented. AAPH (2,2'-azo-bis(2-amidinopropane)dihydrochloride) was used ...
-
(2009)An oxygen radical absorbance capacity (ORAC) method based on pyrogallol red bleaching (ORAC-PGR) was used to evaluate the scavenging activity of berry extracts (blackberry, blueberry, and raspberry). Among berry extracts, ...
-
(2003)Linear solvation energy relationship, LSER, and theoretical linear solvation energy relationship, TLSER, formalisms are applied to the analysis of solvent effects on singlet oxygen reactions. Treatments allow quantitative ...

(2002)The effect of Boldo and black tea infusions on the pro-oxidant effects of vitamin B-2, riboflavin (R-F), when exposed to the action of visible light was studied. The amounts of antioxidants present in Boldo and tea infusions ...

(2011)The bleaching of the pyrogallol red (PGR) dye mediated by superoxide anion radicals (O2-) generated from the xanthine/xanthine oxidase system (X/XO) was studied by UV-visible spectrophotometry. The absorption band (at 540 ...

(Royal Society of Chemistry, 2015)© The Royal Society of Chemistry 2015.In the present work we demonstrate from kinetic studies that under the experimental conditions proposed for the ORAC protocol, ORAC values do not correlate with the capacity of ...
