Abstract
Lycium barbarum polysaccharide were extracted by the methods of water extracting,and the optimum extraction technology was determined by orthogonal experiments.The optimum parameters to extract were as follows: the extracting time 5h,temperature 100℃,ratio of water to material 1∶40;With microwave-assisted extraction for over 25 minutes,the extraction percent will reach 15.91%;Extraction concentrated to proper volume was precipitated with 4 times volume of 95% ethanol for 4 hours.
