Analysis of derivatives of carbohydrates by high-pressure liquid chromatography

Abstract

The behaviour of benzoylated derivatives of alditols, monosaccharides, disaccharides, amino sugars, and methyl glycosides in high-pressure liquid chromatography (h.p.l.c.) has been investigated. A system was devised, using the most basic equipment of a single pump and fixed-wavelength u.v. detector, which gave good separations of the components of mixtures of derivatised methyl glycosides. Fractionation of complex mixtures of many of the other benzoylated carbohydrates was achieved in less than 30 min. The 4-nitrobenzoates were less useful for routine analyses.
