| 摘 要： | 分析了不同品种桑椹的糖酸组分。以33个品种桑椹的果实为试材,利用高效液相色谱技术检测,相关性分析采用相关系数法,聚类分析采用快速聚类法。结果表明,果糖和葡萄糖是桑椹的主要糖类,同一品种二者含量相当,品种之间存在差异,没有发现桑椹中含有蔗糖。所有桑椹品种含有柠檬酸、苹果酸、琥珀酸、草酸、丙酸和富马酸,绝大部分品种含有酒石酸,部分桑椹品种含有丙酮酸,柠檬酸、苹果酸和琥珀酸是桑椹中含量较高的3种有机酸,柠檬酸质量分数为41.30%～68.80%。总酸与柠檬酸、苹果酸和琥珀酸呈极显著正相关(p<0.01)。33个品种桑椹可分成五大类群,分别由10,1,5,7,10桑椹品种组成。

| Abstract: | This paper analyzes the sugar and acid compositions of different mulberry cultivars.Fruits of 33 mulberry(Fructus mori.) cultivars are detected by HPLC methods.And a fast clustering procedure and a corelation coefficient analysis are used for experimentation.The results show that both fructose and glucose are soluble sugars in the mulberry while sucrose aren't detected.The contents of fructose and glucose of the same cultivars almost are equal.All cultivars contained citric acid,malic acid,succinic acid,oxa... |
