ABSTRACT
The technique of extracting and refining mucopolysaccharide from Dasyatis akajei cartilage obtained was studied and the content of mucopolysaccharide was measured.The results showed that when the content of NaOH was 6%,temperature 40℃, extracting time 6h,followed neutral protein enzyme dissolution for 7h under 40℃,protein precipitation with trichloroacetic acid and 4 times volume 95% C_(2)H_(5)OH for polysaccharide precipitation.the extraction rate was over 21%, the product was white powder and its purity was about (84.53%).Physical and chemical properties of the mucopolysaccharide were identified.
