【摘要】 通过对灰树花菌丝体进行多糖的提取、分离纯化,得到多糖G.F.-1。研究表明,G.F.-1是一种均一性好、分子量为1.23×106的大分子纯多糖,其单糖组成的摩尔比为Xyl∶Man∶Glc=0.9∶1.4∶4.7;一级结构是主链中β(1→3)、β(1→6)糖苷键为主,分枝点主要发生在C6位的β-D-葡聚糖所构成。更多还原

【Abstract】 Polysaccharide was extracted from Grifola frondosa Mycelia then isolated and purified a nd fimally.G.F.-1was obtained.The results showed that G.F.-1was a kind of pure poly saccharide and large molecule that had better consistency,In addition,its Molecular weight was 1.23×10 6 and mol ratio of sugar composition was Xyl∶Man∶Glc =0.9∶1.4∶4.7respectively.Its first stru cture was made ofβ-D -Glc with the main chain bonds ofβ(1→3)andβ(1→6),where the substitutional ramification mostly took place in C 6 .更多还原
