The comparison of the main nutrients and elements among three kinds of jujube fruit

Difference of main nutritional composition and elements among lingbao,xinzheng,xinjiang jujube fruit was found out. [Methods]: The main nutrients content were detected by chemical methods. The content of Ca,Mg,Cu,Fe,Co,Li,Zn,Se,Mn were determined by inductively coupled plasma emission spectrometer. [Results]:In xinjiang jujube,VC,Protein,total sugar,polysaccharide,Se content were the highest among three kinds of jujube fruit. In lingbao jujube fruit,fat,total acidity,flavonoids content,the content of Ca,Fe,Mg,Zn,Co were the highest. Cu content in xinzheng jujube was the highest. [Conclusions]: Compared three kinds of jujube fruit,xinjiang jujube is rich in nutrients content,lingbao jujube is rich in elements.
