A water soluble β-glucan (GLSWA-I) with a weight average molecular weight ∼1.57×10g/mol, isolated from the aqueous extract of the broken cellular wall Ganoderma lucidum spores, was purified by anion-exchange and gel-permeation chromatography. The immunological activity test in vivo showed that GLSWA-I could significantly promote dinitrochlorobenzene (DNCB) induced delayed-type ear swelling in mice. Based on the monosaccharides composition analysis, methylation analysis, IR, 1D and 2D NMR spectroscopy, the repeating unit of polysaccharide GLSWA-I was elucidated as follows.
一种水溶性β-葡聚糖(GLSWA-I),其重均分子量约为 1.57×10g/mol,从灵芝孢子破壁细胞提取液中分离得到,通过阴离子交换和凝胶渗透色谱进行纯化。体内免疫活性试验表明,GLSWA-I 可显著促进二硝基氯苯(DNCB)诱导的小鼠迟发型耳部肿胀。根据单糖组成分析、甲基化分析、IR、1D 和 2D NMR 光谱,多糖 GLSWA-I 的重复单元如下所示。
