中文摘要：
采用三维激发发射荧光光谱结合自加权交替三线性分解（SWATLD）二阶校正方法,对人体液样（血浆样及尿液样）和细胞培养基样中五味子甲素的含量进行了直接快速定量分析.在血浆背景、尿液背景和细胞培养基背景共存下,当分析体系的组分数分别选择2时,用SWATLD二阶校正方法获得相应五味子甲素的平均回收率分别为（100.4±1.6）%,（100.5±6.3）%和（103.6±4.5）%.实验结果表明,此方法不仅能够较好地解决这些复杂分析体系因背景内源荧光性物质与待分析物光谱严重重叠所引起的难分辨的问题,还可以用于直接快速准确定量分析.
英文摘要：
A novel method for quantitative analysis of Schizandrin A in body fluids and cell culture media is presented and discussed in this paper.Three-way data was analyzed by second-order calibration method based on self-weighted alternating trilinear decomposition（SWATLD） algorithm.Satisfactory results have been achieved,fully exploiting ／!second-order advantage／＂.The average recoveries of Schizandrin A in human plasma samples,urine samples and cell culture media by SWATLD with component number N=2 are（100.4±1.6）%,（100.5±6.3）% and（103.6±4.5）%,respectively.It could be applied to quantitative analysis of Schizandrin A even in the presence of unknown interferences,without time-consuming and complicated pretreatment procedure.
