A rapid and quantitative method for the simultaneous measurement of uric acid, ascorbic acid, and related metabolites in biological fluids is described. This method makes use of anionexchange extraction columns to isolate the desired compounds from a wide range of biological fluids, and anionexchang
5-Aminolevulinic acid (ALA), the common precursor of all naturally occurring tetrapyrroles, forms a stable condensation product with 2-amino-3-hydroxynaphthafene which can be identified by its fluorescence. Separation of the compound by reversed-phase high-performance liquid chromatography on RPC-18
The stoichiometry of the formation of hydrogen peroxide from ascorbic acid in a model wine system has been examined by square-wave voltammetry (SWV) on a hanging mercury drop electrode. Both ascorbic acid and hydrogen peroxide could be determined in the same test sample by first employing an anodic
