A simple approach to the determination of three curcuminoids with similar chemical structures in different substrates.

ABSTRACT: The determination of curcuminoids in mixtures is more difficult due to their similar chemical structures as well as serious interferences, thus the complex pretreatments of samples and the optimization of experimental conditions are often required. Here, owing to the mathematical separation of chemical signals by Tchebichef image moments, a simple and effective approach to the simultaneous quantitative analysis was proposed, and applied to the determination of the three curcuminoids in turmeric and curry based on their raw fluorescence 3D spectra. For the established linear models, the leave-one-out correlation coefficients (R _loo-cv) were more than 0.9816 within the linear ranges, and the predictive correlation coefficients (R _p) for the external indepe
