<正>用磷酸盐浸润硅胶薄层色谱法对葡萄糖、木糖、甘露糖、阿拉伯糖和半乳糖进行了分离与定性试验。结果表明,使用浙江硅胶能使这些单糖混合液完好地分离。点形好,也未发现拖尾现象。R_f值基本一致,说明重现性较好,从而有可能进一步定量木材和纸桨水解液中的单糖。

Some separative and qualitative tests have been made for glucose, mannose, xylose, arabinose and galatose by thin-layer chromatography on phosphate impregnated kie2 selqur. Results show that mixed liquids of simple sugars can be well separated by kieselqur which is made in Zhejiang Province. Spots form well; no tails are found. Rf values are almost the same, which gives better reproducibility; hence, there exists possibility of determining sugars quantitatively in wood and pulp hydrolysates.
