摘要
烟草及烟用香精香料中氨基酸的含量对烟草品质有着直接而重要的影响,因此有必要进行准确定性定量分析.氨基酸检测方法可分为直接检测法和间接检测法两大类,间接检测法又可分为柱前衍生法和柱后衍生法.分析了每种方法的优缺点以及常用的衍生化试剂,以期为进行氨基酸分析的研究者提供参考.
The content of amino acids in tobacco and tobacco flavor has a direct and important effect on the quality of tobacco,so it is necessary to carry out accurate qualitative and quantitative analyses.Methods for the amino acid analysis can be divided into two types:direct analysis and indirect analysis,the latter includes pre-column derivatization and post-column derivatization.The advantages and disadvantages of common methods and derivatization reagents were analyzed,so as to provide reference for the one doing amino acid analysis.
