摘要
[目的]分析不同品种枣果实多糖含量,筛选多糖含量高的枣果资源,促进枣果资源的综合开发利用。[方法]以鸡蛋枣、糖枣、药枣、长枣等16个湖南主要地方枣品种为试材,经硫酸-苯酚法对不同品种枣果实多糖含量进行了分析测定。[结果]分析表明,,其中以小米枣和子代糖枣多糖含量最高,%、%;母本糖枣、酸元枣、药枣、长枣、玉泉八号和南方冬枣次之,多糖含量分别为
%、%、%、%、%、%;而光皮枣多糖含量最低,%。不同枣品种间多糖含量差异较大。[结论]研究显示,苯酚-硫酸法较为稳定,正确率和精密度高,重现性好,可作为枣多糖含量的测定方法;同时,枣具有很高的多糖加工利用价值,值得开发利用。

Abstract [Objective] To analyze haride content in different varieties of jujube fruit, screen out jujube fruit resources with high haride content and promote prehensive development and utilization. [Method] Taking Hunan local variety egg jujube, candied jujube, medicinal jujube, long jujube kinds of jujube cultivars as materials, the haride content in different jujube cultivars were determined by sulfuric acid phenol method. [Result] The highest and the lowest haride content in different varieties of jujube fruit reach times, among which, millet jujube and filial generation candied jujube has the highest haride content of %, % respectively; The secondly were the female candied jujube, acid yuan jujube, medicinal jujube, long jujube, Yuquan and southern Dongzao, respectively, %, %,

%, %, %, %, and the light skin jujube content is the lowest, only %. The haride content in different varieties of jujube fruit has significant differences.
[Conclusion] The study showed that, sulfuric acid phenol method is stable with high accuracy, precision and good reproducibility, which can be used for determination of haride content in jujube; meanwhile, jujube has highe
