[Objective]To isolate and purify polysaccharide from wild Lycium barbarum of Shandong Province,and analyze its components.[Method] LBP was extracted from Lycium barbarum with water and purified with DEAE ion-exchange cellulose column and Sephadeex G-100 column.The content of Lycium barbarum polysaccharide(LBP) was determined with phenol-sulfuric acid method and the components were analyzed with FTIR spectrometer.[Result] LBP content of wild Lycium barbarum from Shangdong Province was 12.56%.LBP contained 4 water soluble polysaccharides like LBP-Ⅰ,LBP-Ⅱ,LBP-Ⅲ and LBP-Ⅳ.[Conclusion]The study would provide basis for further study on the structural characteristics and function of Lycium barbarum polysaccharide.
