摘要
近年来多糖在治疗癌症、爱滋病和减缓衰老等领域的免疫调节作用引起国际上的广泛关注[1].
An alkaline soluble polysaccharide R-1 has been obtained by extraction with 2%NaOH from marasmius androsaceus FR. and purified by chromatography on Sepharose CL-4B and HPLC. The GC-MS analysis showed it appeared constructed from glucan. Through periodate oxidation, Smith degradation, methylated analysis and ~13C NMR it revealed that R-1 has 1→3 Glc as main chain and 1→6 Glc as side chain. The inhibition percentage against S-180 tumor of R-2, which was obtained by elemination of its side chains, was 92.8%.
