Description	A new separation method based on the combination of exclusion and ion exchange chromatography in borate buffer was developed. It allows semi-preparatory and preparatory separation of isobaric N-acylhexosamines (C-2 epimers) and corresponding methyl glycosides (anomers and tautomers). Three types of polyolic gels were tested for these separations. Ion-exchange HPLC was used as a rapid and reliable method for the quantification of the respective analytes. NMR studies of the interactions of N-acetylhexosamines with borate confirmed the importance of a proper stereochemical arrangement of acetamido sugars for their interactions with borate anions A new separation method based on the combination of exclusion and ion exchange chromatography in borate buffer was developed.

Umožňuje semipreparativní a preparativní separaci N-acetylhexosaminů (C-2 epimerů) a odpovídajících methylglykosidů (anomerů a tautomerů). Byly testovány tři typy polyolických gelů. Iontově-výměnná HPLC byla využita jako rychlá a spolehlivá metoda pro kvantifikaci odpovídajících analytů. Interakce N-acetylhexosaminů s borátem byly studovány pomocí NMR (cs)
