| 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,不同枣品种间最高与最低多糖含量相差达3.9倍,其中以小米枣和子代糖枣多糖含量最高,分别达9.75％、9.06％;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8.82％、6.20％、5.89％、5.56％、5.54％、5.23％;而光皮枣多糖含量最低,仅为2.45％.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 polysaccharide content in different varieties of jujube fruit,screen out jujube fruit resources with high polysaccharide content and promote the comprehensive development and utilization.Method] Taking Hunan local variety egg jujube,candied jujube,medicinal jujube,long jujube etc.16 kinds of jujube cultivars as materials,the polysaccharide content in different jujube cultivars were determined by sulfuric acid-phenol method.Result] The highest and the lowest polysaccharide content in different varieties of jujube fruit reach 3.9 times,among which,millet jujube and filial generation candied jujube has the highest polysaccharide content of 9.75%,9.06% respectively; The secondly were the female candied jujube,acid yuan jujube,medicinal jujube,long jujube,Yuquan No.8 and southern Dongzao,respectively,8.82%,6.20%,5.89%,5.56%,5.54%,5.23%,and the light skin jujube content is the lowest,only 2.45%.The polysaccharide content in different varieties of jujube fruit has significant differences.Conclusion] The study showed that,sulfuric acidphenol method is stable with high accuracy,precision and good reproducibility,which can be used for determination of polysaccharide content in jujube ; meanwhile,jujube has higher polysaccharide processing and utilization value,and is worthy of development. |
