Spectrophotometric determination of catecholamines based on their oxidation reaction followed by coupling with 4-aminobenzoic acid [PDF]
Journal of the Brazilian Chemical Society, 2006 A sensitive and simple spectrophotometric method for the determination of dopamine, methyldopa, levodopa and catechole in either pure form, pharmaceutical formulations and in water is described. The method is based on their oxidation reaction with periodate followed by oxidative coupling with 4-aminobenzoic acid at pH 4 leading to the formation of ...

Enzymatic method for selective determination of 4-aminobenzoic acid in urine [PDF]
Clinical Chemistry, 1990 Abstract We developed a method for the selective determination of 4-aminobenzoic acid by use of 4-aminobenzoate hydroxylase (EC 1.14.13.27) to convert 4-aminobenzoic acid to 4-hydroxyaniline. The subsequent conversion of 4-hydroxyaniline to indophenol dye was quantified colorimetrically. The method is reproducible, and the assay response
