A 3,6-dinitrophthalic acid colour reaction was used for determination of reducing sugars. Charcoal column chromatography separated honey sugars into the following 3 fractions: (1) aqueous eluate (glucose and fructose); (2) 7% ethyl alcohol eluate (disaccharides); (3) 50% ethyl alcohol eluate (higher oligosaccharides).
