摘要: 对枸杞子水溶性粗多糖进行了分离提纯和化学构造研究。除了已经报道过的4种糖蛋白AGP(Arabinogalactan-protein:Cp-1-C,Cp-1-D,Cp-2-B和Hp-2-C)外,还得到了一种均一的阿拉伯聚糖(Hp-0-A,分子量23,000)。运用甲基化分析及其NMR技术确定了其主要构造特征。

Abstract: In addition to 4 kinds of polysaccharides AGP (Arabinogalactan-protein: Cp-1-C, Cp-1-D, Cp-2-B and Hp-2-C) already reported, another water-soluble araban (Hp-0-A, Mw=23,000) was isolated from the fruit of Lycium chinense Mill. The result of glycosyl residues analysis indicated that it had a backbone of (1→5)-L-araban, and some of the L-arabinofuranosyl residues were involved in the branches through O-3. There was good conformity between the results obtained by chemical and NMR spectroscopic methods.
