The formation of colored products by the reaction of sugars and phenols in the presence of strong acids has been mentioned previously as a qualitative test for carbohydrates. Carbazole or anthrone may be used instead of a phenol. Methods employing orcinol (3,5-dihydroxy toluene) and carbazole have been described in detail 31). Dische 32) described a modified carbazole reaction for determining ketohexoses, ketopentoses, trioses, and glycolic aldehyde as well as a method for determining heptoses. [Pg.617]
