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, ...
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 ...
The characterization of a thermostable and cambialistic superoxide dismutase from thermus filiformis
(2013-07-01)
The superoxide dismutase (TfSOD) gene from the extremely thermophilic bacterium Thermus filiformis was cloned and expressed at high levels in mesophilic host. The purified enzyme displayed approximately 25 kDa band in 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 ...
