不同枣品种果实中功能性成分含量的比较研究

Quality evaluation of functional components in different cultivars jujube

采用紫外分光光度法对10个枣品种果实中总黄酮、总酚、三萜和皂苷等活性物质成分含量进行测定分析,评价不同枣品种果实功能性产品的开发价值。结果表明,10个枣品种果实中总黄酮、总酚、三萜和皂苷含量平均值分别为3.07、17.39、39.45、30.50 mg/g,相关性分析显示三萜含量与皂苷含量呈极显著的正相关。不同枣品种各活性物质成分含量对比和对应分析结果均显示,总黄酮与总酚含量最高的枣品种分别为灰枣优株、京39,三萜与皂苷含量最高的枣品种均为赞2与骏1。灰色关联度法研究表现为枣果实中功能性成分含量综合表现较高的枣品种依次为赞2、灰枣优株、京39、中枣1号、骏1,可作为新疆枣功能性产品开发的适宜品种。

The contents of active constituents such as total flavonoids,total phenols,triterpenes and saponins in 10 jujube cultivars were determined by UV spectrophotometry to clear the potential values of functional products in different jujube cultivars. The results showed that the average contents of total flavonoids,total phenols,triterpenes and saponins in 10 jujube cultivars were respectively 3.07,17.39,39.45 and 30.50 mg/g. The triterpenoid content was positively correlated with the saponin.The highest content of total flavonoids and total phenols was respectively Huizao excellent strains,Jing 39,The content of triterpenes and saponins was significantly higher in both Zan 2 and Jun 1.Gray relational analysis selected out the better cultivars with more comprehensive functional components,the top five were Zan 2,Huizao excellent strains,Jing 39,Zhongzao1 hao,Jun 1,which could be used as a ssuitable variety for the development of xinjiang jujube functional products.
