Simple and rapid catalytic spectrophotometric determination of superoxide anion radical and superoxide dismutase activity in natural medical vegetables using phenol as the substrate for horseradish peroxidase
Anal Bioanal Chem (2004) 378: 523-528，-0001，（）：
The coupling reaction of 4-aminoantipyrine (4-AAP) with phenol using the superoxide anion radical(O-*2 ) as oxidizing agent under the catalysis of horseradish peroxidase (HRP) was studied. Based on the reaction, produced by irradiating vitamin B2 (VB2) was spectrophotometrically determined at 510nm. Under the optimum experimental conditions, the relationship between A510 and O-*2 concentration was linear in the range 9.14
