WebIn chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed. WebOn the basis of the xanthydrol reaction and a highly sensitive thin-film chromatographic detection method, content and composition of glycoside metabo…
