Polysaccharide is extracted from Lycium barbarum and the content is determined.Extracting technologies of Lycium barbarum polysaccharide(LBP) of primary study are finished with a single factors and orthogonal test in different experimental groups(hot-water and microwave method),the effects of various factors,such as ration of liquid to solid,temperature,extraction time and the extraction time etc.on the producing rate of Lycium barbarum polysaccharide are compared at given conditions.The optimal conditions ...
