1-Phenyl-3-methyl-5-pyrazolone (PMP) derivatives of component monosaccharides in glycoproteins (fucose, galactose, mannose, N-acetylgalactosamine and N-acetylglucosamine) and epimeric aldopentoses (arabinose, lyxose, ribose and xylose) were well separated from each other by capillary electrochromatography on a Hypersil ODS column with a mixture of 50 mM N-(2-hydroxyethyl)piperazine-2'-(2-ethanesulfonic acid) buffer, pH 6.0 to approximately 6.3, and acetonitrile (2.2:1 v/v) as eluent. The elution of these compounds showed relatively strong dependence on the pH and concentration of the buffer salts contained in the eluent, as compared to the elution by pressure-driven high-performance liquid chromatography (HPLC) on the same stationary phase, but separation of PMP-monosaccharides was better than that by HPLC. Retention times of PMP-monosaccharides were highly reproducible with a relative standard deviation (RSD) of approximately 0.6%, and quantification with an RSD less than 5% could be achieved using 3-O-methylglucose as an internal standard.
