RELEVANCE OF SECONDARY PROCESSES IN ORAC VALUES OBTAINED EMPLOYING PYROGALLOL RED AS TARGET MOLECULE
(Sociedad Chilena de Química, 2009)
Ascorbic acid contribution to ORAC values in berry extracts: An evaluation by the ORAC-pyrogallol red methodology
(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, ...
USE OF THE ORAC-PYROGALLOL RED/ORAC-FLUORESCEIN RATIO TO ASSESS THE QUALITY OF ANTIOXIDANTS IN CHILEAN WINES
(SOC CHILENA QUIMICA, 2011)
We have recently proposed that ORAC (Oxygen Radical Absorbance Capacity) methods employing fluorescein (ORAC-FL) and pyrogallol red (ORAC-PGR) as target molecules could be considered as complementary indexes. In particular, ...
NADPH oxidase activity: Spectrophotometric determination of superoxide using pyrogallol red
(Academic Press Inc., 2017)
© 2017 Elsevier Inc.A simple and fast spectrophotometric methodology able to quantify superoxide released by NADPH oxidase from differentiated promyelocytic leukaemia (HL-60) cells using pyrogallol red is described.The ...
Antioxidant capacity of phenolic compounds in acidic medium: A pyrogallol red-based ORAC (oxygen radical absorbance capacity) assay
(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 ...
Pyrogallol red oxidation induced by superoxide radicals: application to evaluate redox cycling of nitro compounds
