摘要
提出一种三维荧光结合基于交替三线性分解(ATLD)算法的二阶校正方法快速对人体血清和尿液中的两种抗丙型肝炎药物达卡他韦(DAC)和雷迪帕韦(LED)进行定性定量的分析方法。二阶校正方法因具有"二阶优势",可避免复杂的样本预处理,即使分析物之间和分析物与未知干扰之间存在严重的光谱重叠,该方法仍可得到满意的定性定量结果。两种药物的平均回收率为98.35%~109.95%,相关系数大于0.99。同时,相应的品质因子参数反映出该方法具有较高的灵敏度,较好的选择性和较低的检测限。这一方法的建立有望为临床药物的快速分析提供新思路。
This work proposed an analytical method that three-way fluorescence coupled with second-order calibration based on alternative trilinear decomposition(ATLD) algorithm to rapidly and simultaneously quantify two anti-hepatitis C drugs including daclatasvir(DAC) and ledipasvir(LED) in human serum and urine. Using the "second-order advantage" of the second-order calibration method can avoid complicated sample pretreatment.Even if the fluorescence spectra of interested analytes overlapped and unknown interference coexisted in the system, the method can still require satisfactory qualitative and quantitative results. The average recoveries were98.35%~109.95%, and the correlation coefficients were more than 0.99. The figures of merit also showed that the method has higher sensitivity and better selectivity and lower limit of detection. The establishment of this method is expected to provide new ideas for the rapid determination of clinical drugs.
