已定义混合酸性二苯胺-苯胺喷雾剂在纸色谱上与糖醛酸、庚醛糖、甲基戊糖和戊糖发生特定颜色反应的条件。当试剂以两次连续喷雾方式施用时，即先使用二苯胺，然后使用苯胺，会与 (1) 所有己醛糖和还原己醛糖发生额外的特定颜色反应 二糖（含有 1,4-键的除外）和 (2) 以及一些酮糖。该分裂试剂能够清楚地区分l-山梨糖和d-果糖。讨论了颜色形成中可能发生的反应。
Conditions have been defined in which mixed acidic diphenylamine-aniline sprays give, on paper chromatograms, specific colour reactions with uronic acids, aldoheptoses, methyl pentoses and pentoses.When the reagents are applied as two successive sprays, i.e. diphenylamine followed by aniline, additional specific colour reactions are obtained with (1) all aldohexoses and reducing aldohexose disaccharides (other than those containing a 1,4-link) and (2) with some ketoses. This split reagent is able to distinguish clearly betweenl-sorbose andd-fructose.The possible reactions involved in the formation of the colours are discussed.
