Title: Further exploration on the paper chromatography of amino acids
Abstract: Traditional paper chromatography can be divided into two separated steps:chromatography and color development.This brings a lot of inconvenience.This paper investigates the experimental conditions of the connection between chromatography and color development,and screens a new chromatographic solution consisting of 70g phenol,30g water and 0.14g ninhydrin,which can be kept for long time.Both the separation effect of chromatography and the background is very well.Moreover, the results shows that ninhydrin can inhibit the oxidation of phenol,which solves the difficulty of easy oxidation of phenol.
