| Abstract: | OBJECTIVE To study the optimum cendition of extraction polysaccharide from Anoectohilus formo-sanus by thin alkali method.METHODS The content of polysaccharide was determined by DNS Method.With the content and yield of polysaccharide as indexes ,investigate the influencing factors of polysaccharide from Anoectohilus formosanus in the process of extraction and precipitation were investigated.RESULTS The optimum extraction con-dition of polysaccharide from Anoectohilus formosanus was obtained as follows：extraction temperature was 70℃,ex-traction time was 2 hours,ratio of material to liquid was 1∶35,extraction twice,standing time was 5 hours,and centri-fuge for 5 minutes by 7000 rpm.CONCLUSION The thin alkali method for extraction extracting polysaccharide from Anoectohilus formosanus was proved to be a high efficiency and stable method. |
