title: Quantitative analysis of hyaluronic acid by high-performance liquid chromatography of streptomyces hyaluronidase digests.
abstract: The separation and quantitative analysis of streptomyces hyaluronidase ( HAase ) degradation products of hyaluronic acid (HA) by high-performance liquid chromatography are described. The substituted 4,5-unsaturated tetrasaccharide and hexasaccharide which result from the digestion of HA are quickly separated on a silica gel (Zorbax SIL) column. The assay of HA is linear between 5 and 250 micrograms of HA. This procedure is suitable for some weakly acidic glycosaminoglycan contaminants having similar properties to those of HA.
