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.
