Abstract

Abstract: The concentration of reserpine in urine was directly and quantitatively measured with the excitation-emission fluorescence(EEM) combined with three-dimensional calibration methodologies. Two calibration methodologies are based on the alternating trilinear decomposition(ATLD) and the self-weighted alternating trilinear decomposition(SWATLD) algorithms, respectively. The satisfactory results of both methods are obtained, when the component number was chosen to be 3(N=3). This experiment is easily carried out without time-consuming and complicated pretreatment. It proved that ATLD and SWATLD based three-dimensional calibration methodologies can be feasible to directly quantify the medical content of reserpine in urine
