Spectrophotometric determination of ritodrine and isoxsuprine hydrochlorides using 4-aminoantipyrine.
A simple, accurate, and rapid method for the quantitative determination of ritodrine hydrochloride (RTH) and isoxsuprine hydrochloride (ISH) in both pure and dosage forms, is described. The method is based on the development of pink colored product as a result of the condensation of 4-aminoantipyrine with phenols in the presence of an alkaline oxidizing agent. The resulting products are measure...
متن کاملDetermination of polyphenols in wines by reaction with 4-aminoantipyrine and photometric flow-injection analysis.
A new flow-injection analytical procedure is proposed for the determination of the total amount of polyphenols in wines; the method is based on the formation of a colored complex between 4-aminoantipyrine and phenols, in the presence of an oxidizing reagent. The oxidizing agents hexacyanoferrate(III), peroxodisulfate, and tetroxoiodate(VII) were tested. Batch trials were first performed to sele...
متن کاملThe determination of serum acid and alkaline phosphatase activity with 4-aminoantipyrine (A.A.P.).
C6H5 Gottlieb and Marsh (1946), using alka:ine ferricyanide as the oxidant, devised a method for the estimation of certain phenolic fungicides with A.A.P. The procedure was modified by Grifols (1951) for the determination of phenol in the measurement of alkaline phosphatase activity in body fluids. This author made a careful study of the factors which control the development of the colour and h...
متن کاملEnzymatic blood glucose determination by colorimetry of N,N-diethylaniline-4-aminoantipyrine.
The hydrogen peroxide produced from glucose by glucose oxidase action at pH 7 is determined by the peroxidase oxidative coupling of N,N-diethylaniline with 4-amino-antipyrine. A 20-al sample of plasma or serum is reacted at room temperature for 10 mm. The sensitivity of the method is such that 60 zg of glucose (300 mg/dl) in a final volume of 5 ml gives an absorbance of 0.8 at 553 nm with a 1-c...
متن کاملSpectrophotometric determination of phenylephrine hydrochloride in pharmaceuticals by flow injection analysis exploiting the reaction with potassium ferricyanide and 4-aminoantipyrine.
This paper presents a method for the determination of phenylephrine hydrochloride in pharmaceuticals by spectrophotometric flow injection analysis exploiting the reaction with potassium ferricyanide and 4-aminoantipyrine, which leads to the formation of a condensation product with strong absorptivity at 500 nm. The linear dynamic range was between 0.95 and 9 mg/L, with a limit of detection of 0...
