Purification and Identification of Polysaccharide from Papaya

WANG Xiao-mei et al(School of Life Science,Huzhou Teachers College,Huzhou,Zhejiang 313000)  
[Objective] The extraction,purification and identification of polysaccharide from papaya were studied so as to provide reference for the comprehensive application of papaya.[Method] Polysaccharide was extracted with the method of water extraction and alcohol precipitation,and the protein was dispelled with the sevage method and the content of protein and starch was measured.[Result] The results showed that the optimum extraction craft was when the temperature was at 90 ℃,solid-liquid ratio of 1∶50,time of 2.5 h,and the polysaccharide yield was up to 8.61%.[Conclusion] There were no protein,starch and polyphenol in polysaccharide from papaya.The method of water extraction and alcohol precipitation was available for the utilization of papaya.
