纸色谱和薄层色谱是分离和鉴定氨基酸的重要方法之一［１］。经典的方法常依次分为点样、饱和、展开、显色及结果分析五个实验步骤［２］，其不足在于时间长，试剂消耗大，本文从简便、经济的角度出发，对氨基酸的纸色谱和薄层色谱进行了研究，获得了较好的效果。１实验部... Paper chromatography and thin-layer chromatography is one of the important methods for the separation and identification of amino acids [1]. The classical methods are often divided into five experimental steps of spotting, saturation, expansion, color development and result analysis [2]. The disadvantage of this method is that it takes a long time and consumes a large amount of reagents. In this paper, from the point of view of simplicity and economy, Chromatography and thin layer chromatography were studied and obtained good results. 1 Experimental Department ...
