| 摘 要： | 灵武长枣样品经脱脂,脱小分子糖后,用蒸馏水沸水浴浸提、醇沉、洗涤得灵武长枣多糖,含量测定采用苯酚-硫酸比色法,用精制多糖测得其多糖对葡萄糖的换算因子。建立了一种简便、准确测定灵武长枣多糖含量的方法。结果表明:该方法测定简便可行,重现性较好,平均回收率为97.11%,所测全红灵武长枣样品中多糖含量为13.30%。

| Abstract: | With ungrease treatment and oligo-saccharide,and extract by boiling water-bath,ethanol precipitation,deprivate protein,and determinated its content by phenol-sulfuric acid method.This experiment established a simple,accurate determination method of polysaccharide form Zizyphus jujuba Mill cv.lingwuchangzao.The results showed that it was a simple,feasible method to determinate polysaccharide content,the recovery was 97.11%,the polysaccharide in Zizyphus jujuba Mill cv.lingwuchangzao was 13.30%. |
