中文摘要: 以山西红枣壶瓶枣、板枣、木枣为材料，利用氨基酸自动分析仪对红枣果肉中的17种氨基酸含量进行测定，红枣总氨酸含量最高的是木枣（45.88±2.11）mg/g，其次是板枣（39.78±3.17）mg/g，壶瓶枣最低（39.76±1.63）mg/g。通过方差分析表明，不同品种红枣的氨基酸含量差异不显著，但同一品种红枣之间的氨基酸含量差异显著。同时利用主成分分析提取了3个主成分，依据各主成分得分值与方差贡献率建立综合评价模型，得到3个品种红枣氨基酸含量的综合得分，由高到低依次为板枣、壶瓶枣、木枣。
Abstract:The contents of 17 kinds of amino acids in the pulp of jujube were determined by automatic amino acid analyzer.The highest content of total amino acids in jujube was Mu jujube（45.88 ± 2.11）mg/g，the second was Ban jujube（39.78±3.17）mg/g，the lowest was Huping jujube（39.76±1.63）mg/g.The analysis of variance showed that the contents of amino acids in different cultivars were significantly different，and the contents of amino acids in the same cultivars were also significantly different.At the same time，three principal components were extracted by principal component analysis，and a comprehensive evaluation model was established according to the principal component scores and the contribution rate of variance，from high to low order was Ban jujube，Huping jujube，Mu jujube.
