Abstract
Three-dimensional strategies involving the application of parallel factor analysis (PARAFAC) to the kinetic UV absorbance measurements were elaborated to monitor the oxidation of quercetin with oxidant agents (K2Cr2O7 and KIO3) and to quantify analyte in a dietary supplement product. Loadings (spectral, kinetic and concentration profiles) were obtained by the PARAFAC deconvolution. Spectral identification, kinetics and quantification of the relevant analyte in the presence of interferent(s) were performed. The elaborated chemometric strategies were carefully validated to demonstrate the capability of the method. Assay results of the PARAFAC strategies were statistically compared to that of the newly developed UPLC method.
