摘要: 榛蘑烘干后经热水提取,乙醇沉淀得粗多糖。粗多糖经Sevag法除蛋白后上DEAE-纤维素(OH-)柱层析,分离得到五种多糖组分Am-I、Am-II、Am-III、Am-IV和Am-V,SepharoseCL-4B测得Am-I分子量为1.46×104,红外光谱和NMR波普分析表明Am-I为含有葡萄糖醛酸的主要以β(1,3)糖苷键和β(1,6)糖苷键连接的D-吡喃葡聚糖。邻苯三酚自氧化法测定榛蘑粗多糖和Am-I均具有清除氧自由基的作用。

Abstract: The saccharides of Armillaria mellea were extracted by hot water and then deposited by ethanol. The DEAE cellulose column chromatography was used on saccharide purification after the protein was extracted with Sevage method. The results indicated that the saccharides are composed of Am-I, Am II, Am III, Am IV and Am V. The Sepharose CL-4B method showed that molecular weight of Am-I is 1.46×104 when Infrared Ray(IR)and Magnetic Resonance(NMR) assays showed that Am-I is glucopyranose(containsing glucuronic acid), mainly linked byβ(1-3)glucosidic linkage and β(1-6) glucosidic linkage. The pyrogallic acid autooxidation method assay indicated both saccharides and Am-I have anti-oxidant property.
