Determination of L- Ascorbic Acid in Plasma by Voltammetric Method
Voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as L-ascorbic acid (AA). L-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...

متن کاملA Highly Sensitive Kinetic Spectrophotometric Method for the Determination of Ascorbic Acid in Pharmaceutical Samples
In this study, a new reaction system for quantitative determination of ascorbic acid was introduced. The developed method is based on inhibitory effect of ascorbic acid on the Orange G-bromate system. The change in absorbance was followed spectrophotometrically at 478 nm. The dependence of sensitivity on the reaction variables including reagents concentration, temperature and time was investiga...

متن کاملDEVELOPMENT OF A METHOD FOR THE DETERMINATION OF 4-HYDROXY-3-METHOXYMANDELIC ACID (VANILLYLMANDELIC ACID) IN URINE BY PAPER CHROMATOGRAPHY
We have developed a simple and precise paper chromatographic method for the determination of 4-hydroxy-3-methoxymandelic acid (VMA) in urine. Concentrations of VMA in patients with neuroblastoma were increased in comparison to controls. The linearity was excellent in the concentration range tested. The within-assay coefficient of variation for control and patient urine was less than 2.2%. ...
