PURPOSE:A novel polysaccharide derivative soluble in organic solvents, obtained by linking a COOH-containing compound consisting substantially of only one of a pair of optical antipodes which exist to a polysaccharide by ester bond. CONSTITUTION:(A) A COOH-containing compound consisting substantially of only one of a pair of optical antipodes which exist, except amino acid (e.g., one of optical antipodes such as chrysanthemumic acid, l-menthoxyacetic acid, d- tocopheroxyacetic acid, etc.) is esterified with (B) a polysaccharide (e.g., beta-1,4- glucan including cellulose, alpha-2,6-fructan including levan, galactan including agar, etc.), to give a novel derivative (preferably >=50wt% OH in a polysaccharide molecule is replaced with the compound A) wherein the compounds A and B are linked by ester bond. USE:Useful as a carrier for chromatography, a liquid crystal substance, a resolving reagent for optically active substance.
