The nutritional ingredients such as general nutrients, amino acids, minerals, total triterpene, cAMP and flavonoids of Zhanhua winter jujube, Laoling zizyphus jujube, Xinjiang jujube and Quanchenghong jujube were analyzed, respectively. The results indicated that there were 17 amino acids in each of the four kinds of jujubes, 7 amino acids were essential to human life among them, and the four kinds of jujubes were also rich in minerals such as Ca, Na, Mg, K, Fe, Zn, Se, Sr, Cu. For Xinjiang jujube, the soluble solids content 36.50%, the soluble polysaccharide content 31.49%, vitamin C content 1 018.00 mg /100 g and the content of cAMP 26.17 mg /100 g were all higher than the other three jujubes. The content of total triterpene of Quanchenghong jujube was the highest, which was 74.26 mg/100 g; The crude fiber content of Laoling zizyphus jujube was the highest, which amounted to 2.85 g/100 g; The total flavone content of Zhanhua jujube was the highest, which was 404.28 mg/100 g. The contents of different nutrient among different kinds of jujubes are different, which show their different development potential in the medicinal value and commercial production.
