Abstract
A rapid, reliable method based on reversed-phase high performance liqu id chromatography for the qualitative and quantitative determination o f magnesium ascorbyl phosphate (VC-PMG) in both standard solutions and cosmetic products is reported. The procedure, based on an aminic stat ionary phase and acetonitrile-0.3 M phosphate buffer (pH 4) (40:60) as the mobile phase, allows the determination of VC-PMG in cosmetic samp les after dilution with a tetrahydrofuran-0.3 M phosphate buffer (pH 4 ) (3:7) solvent mixture.
