Abstract: A series of inulides from the Jerusalem artichoke (Helianthus tuberosus) can be separated in its individual components of degree of polymerization from 1 to 20 by using the chromatography on silica gel with a solvent system: n-butanol—ethanol—water at a temperature near 50°C. The separated oligosaccharides are determined automatically and continuously at the outlet of the column. This method might be extended and used for the separation of a series of different oligosaccharides with a degree of polymerization equal or exceeding the value of 20.
