摘要
Abstract
Lycium barbarum oligosaccharide was extracted with water, Proteins and polysaccharides in the extrac-tion were precipitated by 95% ethanol. Pigment in the extraction was separated by macroporous resin. Oligosaccha-ride was isolated by DE AE-5PW(30) ion-exchange cellulose and HW-55F,HW-40F gel chromatography. Two poly-saccharides Compound were obtained. According to ESI-MS analysis, the average molecular weights of oligosaccha-rides were estimated to be 666.4 and 504.3. Their structures were Fructose(2→4) Glucose(1→2) Glucose α(4→2) Fructose and Galactose β(1→6)Glucose α(1→2) Fructose which were analyzed by NMR.关键词
