Chen Cunwu,Zhang li,Wang Yuling,Zhu Fangliang(Department of Chemistry and Life Science,west Anhui University,Lu'an,237012 China)  
With partical active carbon as decolorant,the influence of decoloring time,decoloring temperture and the amount of active carbon on polysaccharide yield ratio and discoloration ratio of the extract polysaccharide from Polygonatum were studied in this paper,and the best condition for the discoloration of polysaccharide were also studied.The results indicated that,with the decoloring condition of 50℃,40 min and 2% active carbon,the polysaccharides yield ratio and discoloration ratio were pretty high.
