A simple quantitative procedure for sugar analysis of plant materials by paper chromatography with good reproducibility is described. The alcoholic extract was partially purified by a tertiary solvent system and ion exchange resins and then paper chromatography with the following solvent: water-saturated n-butanol, 95% ethanol and trichloroethylene (6:2:2, v/v). The sugars were selected by a guide strip technique, and eluted from the “cut-out squares” of paper with 3 ml distilled water by a micro-elution tube, here described. Theyb were determined by a micro-colorimetric method. The method permitted 72 determinations to be done at one time. |
