Abstract: The results of enzyme and spectra analyse indicated that the ChS digested from pig laryngeal cartilage contains the repeated structure units of GlcA(β1-3)GalNAc4SO3 and GlcA(β1-3)GalNAc6SO3, it may not have the structure characteristics of keratan sulfate and dermatan sulfate such as NeuAc(α2-3)Gal(β1-4) GlcNAc4SO3 units and GlcA2SO3(β1-3) GalNAc4SO3, GlcA2SO3(β1-3) GalNAc6SO3 untis.

Key words: chondroitin sulfate(ChS), structure elucidation
