摘　　要：生物样品中药物、毒物及内源性物质的定性与定量分析在生命科学和药物研发中发挥重要作用。生物样品的基质复杂,干扰物多,待测物浓度与内源性物质相比明显偏低,且样品取样量少,因此要求生物分析方法的特异性强、灵敏度高、重现性好。二维液相色谱技术具有峰容量大、显著降低复杂样品的基质效应和残留现象,及可以实现样品分析的自动化等特点,已成为生物样品分离分析的有力工具,在环境、食品和药物分析中得到广泛应用。本文在简要介绍了二维液相色谱原理装置基础上,对其在生物样品中药物、毒物和内源性物质分析中的应用进展进行了综述。Qualitative and quantitative analyses of biological samples containing drugs, toxicants and endogenous substances play an important role in the researches of life sciences, as well as in new drug discovery and development. Biological samples are characterized by complex matrix, multiple endogenous interferences, significantly lower concentrations of measured analytes compared to endogenous components and small sampling volume. Consequently, it often requires bioanalysis methods with superior specificity, high sensitivity and good reproducibility. The two-dimensional liquid chromatography （2D-LC） technique, which allows for high peak capacity, significant reduced matrix effect and carryover of complex matrix samples and automated sample pre-treatment and analysis, has been the powerful solution to the separation and analysis of biological sample and widely applied to environment, food and pharmaceutical analysis. On the basis of introduction of the principle and equipments of 2D-LC, the application of this technique in the pharmacokinetics, toxicological and biological study was reviewed.
