Quality evaluation of functional components in different cultivars jujube

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,Zhongzao1hao,Jun 1,which could be used as a ssuitable variety for the development of xinjiang jujube functional products.
