ABSTRACT:
A polysaccharide substance having the following formula is provided: ##STR1## Also provided is a method of producing the polysaccharide substance in which an oligosaccharide having a degree of polymerization from 3 to 10 is chemically bonded to a silane agent at the reducing terminal of the resultant oligosaccharide, the oligosaccharide compound is then polymerized to an average degree of polymerization from 11 to 500 in the presence of an enzyme. Another method for producing the polysaccharide substance is provided in which an aldehyde group at the reducing terminal of an oligosaccharide having a degree of polymerization from 3 to 10 is oxidized with an oxidizing agent, and the saccharide chain of the oxidized product is polymerized to a degree of polymerization from 11 to 500 in the presence of an enzyme, followed by the addition of an acid. The polysaccharide substance has excellent solvent resistance and is useful as a separating agent for chromatography, especially for the separation of chiral compounds.
