Abstract

Abstract Salmon nasal cartilage was micronized in ethanol using a rotor–stator homogenizer for the high yield of proteoglycan extraction. This procedure also brought about depressing the degradation of proteoglycan and the contamination of collagens. Proteoglycan was extracted by 4 M magnesium chloride and isolated by anion-exchange chromatography. The gel filtration HPLC and the antibody reactivity showed that the core protein was intact.
