摘要：

A method is described to separate and characterize neutral and acidic lactose-derived oligosaccharides without prior derivatization or reduction by high-pH anion-exchange chromatography and pulsed amperometric detection (HPAEC-PAD). This method has been applied to human milk oligosaccharides from donors with different blood group specificity (A, Le(a) and A, Le(b)). Neutral and acidic components were separated from each other by anion-exchange chromatography. A distinct separation of individual components was obtained by size-exclusion chromatography on Fractogel TSK HW 50S (acidic oligosaccharides) or Fractogel TSK HW 40S (neutral oligosaccharides containing up to 6 monomers) and Bio-Gel P-4 size exclusion (neutral oligosaccharides containing more than 6 monomers). Furthermore, the molar response factors after HPAEC-PAD have been determined for 28 components.
