摘　　要：以9个主栽枣品种的干果为试材,采用高效液相色谱法,分析了不同枣品种果实中主要糖分及其含量,旨在为枣品种品质评价、品种选择及开发利用方面提供参考依据。结果表明:枣干果中的主要糖组分由蔗糖、果糖、葡萄糖、山梨醇及鼠李糖、木糖及半乳糖的混合物(简称"鼠木半")组成,多数糖组分含量差异显著,不同品种间均表现为蔗糖>果糖>葡萄糖>山梨醇>"鼠木半",阿拉伯糖在所有品种中均未检出;蔗糖是构成枣干果总糖的主要组分,果糖是构成枣果实总糖的次要组分,葡萄糖再次,"鼠木半"和山梨醇所占比例不大;不同品种间糖组分含量差异显著,"灰枣"和"蛤蟆枣"的总糖、蔗糖和果糖含量显著高于其余品种,属于高糖品种。The main sugar components and concentration in fruits of different Chinese jujube cultivars were determined to provide theoretical basis for the jujube fruit quality evaluation,variety selection,resource exploitation and utilization.The dried fruit of nine major jujube cultivars was tested by high performance liquid chromatography（HPLC）.The results indicated that,major components of sugars in dried jujube fruits were sucrose,fructose,glucose,sorbitol and the mixture of rhamnose,xylose and galactose（abbreviated as‘Shumuban’）,arabinose was not detected.Most sugar components were significantly different,the proportion of sugar component in most varieties was similar as following：sucrose〉fructose〉glucose〉sorbitol〉‘Shumuban’.In dried jujube fruits,sucrose made the most contribution to total sugar,followed by fructose and glucose was the third,but sorbitol and‘Shumuban’were quite low in dried jujube fruits.Most sugar components showed significant difference in the detected nine main cultivars.‘Huizao’and‘Hamazao’were high sugar cultivars since they showed significantly higher concentration of total sugar,sucrose and fructose.
