Abstract

PURPOSE:To fractionate hyaluronic acid or a salt thereof in a small width of MW distribution and a desired size, by processing said acid or said salt into a conjugated cpd. with a cationic surface active agent and applying the cpd. to a molecular sieve. CONSTITUTION:Hyaluronic acid or a salt thereof is processed into a conjugated cpd. with a cationic surface active agent. The cpd., dissolved in a water-soluble org. solvent, is fractionated by means of chromatography, and is subsequently dissociated to give a fractionated hyaluronic acid or salt thereof. The cpd. can be obtd. by adding dropwise a cationic surface active agent, e.g., cetyltrimethylammonium halide or cetylpyridinium halide, to an aq. soln. of hyaluronic acid or a salt thereof and mixing them. The chromatography is carried out using, for example, a gel filtration or gel permeation carrier having a desired fractionation MW range and having been washed with an org. solvent of the same kind as the one dissolving the composite. The dissociation of the conjugate is carried out by adding to the fractionated soln. an inorg. salt of an org. acid soluble in the org. solvent used for the fractionation (e.g., sodium acetate).
