Abstract: To clear the nutrition quality of 15 components in Jun jujube from Xinjiang.In this paper, 15 components in Jun jujube from 9 main producing areas Xinjiang were determined.By above data, though INQ (index of nutrition quality) , the nutrition quality of 15 components were studied.The results showed that the INQ of Fe, Zn, Ca, Mg, VB₁, protein, fat, fiber, Mn were less than 1.The INQ of carbohydrate was between 1 to 2.The INQ of Cu in Jun jujube from awati, cele and the INQ of P in Jun jujube from wensu were higher than 1.The INQ of Se in Jun jujube from awati, maigaiti were higher than 2.The INQ of Se in Jun jujube from cele, zepu were higher than 1.The INQ of Cu, P, Se in Jun jujube from other areas were less than 1.The INQ of VB₂ and K were close to or higher than 2.Therefore, Fe, Zn, Ca, Mg, VB₁, protein, fat, fiber, Mn were nutrients needing increasing during developmenting new products with Jun jujube;according to producing areas, determing Cu, P, Se increasing or not.Jun jujube was good souse of VB₂ and K.
