Title: Isolation, purification and identification of Lycium barbarum polysaccharide in northeast area.
Abstract: Isolation,purification and identification of Lycium barbarum polysaccharide in northeasarea were studied in this paper.The result showed that the optimum extraction technology of LBP was the extraction temperature 100℃,pH=11,ratio of material to water 1:20,the extraction time 2h.DEAE-SephadexA-50 purification could obtain high purity LBP-4.The analysis of TLC indicated that LBP-4 was mainly made up of Xyl.,Man.,Glu.and galactose acid.IR spectrum and Congo red analysis showed that LBP-4 possessed the characteristics of carbohydrate absorption peak,which is a complex polysaccharides composed of sugars linking through α-glucoside lindage and β glucoside without three spiral structure.
