Determination of piceid by photochemically induced fluorescence and second-derivative: response surface methodology for the optimization of a liquid-liquid extraction procedure for its analysis in wine samples.

Abstract

trans-Piceid itself is weakly fluorescent, but the fluorescence signal (lambda(exc/em)=260/361nm) is greatly enhanced by UV-irradiation of its hydroethanolic solutions. Employing the photoinduced emission signal at 361nm or the amplitude of the second-derivative-photoinduced emission spectrum, between 353 and 361nm, a linear relation is found in the assayed… (More)
