Structural analysis method of oligosaccharide derivative, and oligosaccharide derivative

摘要

A process for preparing an oligosaccharide derivative from an oligosaccharide mixture, the process being characterized in that the process comprises the steps of (a) introducing a lipophilic group into oligosaccharides of the mixture to obtain a mixture of oligosaccharide derivatives, and (b) treating the oligosaccharide derivative mixture by serotonin affinity column chromatography.
