Study on Composite Enzymatic Extraction of Atractylodes Macrocephala Polysaccharides

Hou Xuan1,Zhou Jiarong1,Tian Yunbo2(1.College of Science,South China Agricultural University,Guangzhou 510642;2.College of Life Science,Zhongkai University of Agriculture and Engineering,Guangzhou 510225,China)  
Composite enzymatic(cellulase and pectase) extraction of atractylodes macrocephala polysaccharides was studied in the paper.The main factors that affect extraction yield in the final product were analyzed,such as enzyma reaction temperature,pH,time and enzyma concentration.By means of orthogonal design,optimum parameters were confirmed as enzyma reaction temperature 50 ℃,enzyma reaction pH 5.0,enzyma reaction time 50 min and enzyma concentration 0.7 %.Under these conditions,the polysaccharides extraction rate was 43.00 %.
