Abstract：Inorder toclarifythedifferencesinnutritionalcomponentsof XiaobaiapricotfruitsinAksu，Bayingol Mongolian Autonomous Prefecture and Turpan in Xinjiang，the nuclear magnetic resonance hydrogen spectrum（ 1H -NMR） analysis of Xiaobai apricotfruit samplesfromthreeproducing areas was carriedouttoclarifythe main chemicalcomponents in theattributionspectrumbasedonnuclearmagneticresonance（NMR）technologyinthisstudy.Thediferentialchemicalcom

ponentsof Xiaobai apricot fruits from three producingareas in Xinjiangwere comprehensively evaluated by principal component analysis and least squares discriminant analysis. Theresults showed that a total of 34 chemical components were identified from the three producing areas，including 11 aminoacids，nineorganicacids，fourcarbohydrates and10 otherchemical components.The overall separation of chemi

cal components of Xiaobai apricot samples in the threeproducing areas wasgood，and the chemical components with great differences were mainly succinic acid，malic acid，arginine，serine，sucrose and D -fructose.The relative contents of sucrose and D -fructoseinXiaobai apricotfruitsinAksuandBayingolMongolianAutonomousPrefecturewererelativelyhigh.TherelativecontentsofserineandmalicacidinXiaobai apricotfruitsfrom Turpan wererelativelyhigh.TherelativecontentofsuinicacidinXiaobai apricotfruits fromBayingolMongolianAutonomous Prefecture washigher.Theresultsofthisstudy provide a basis for the development and utilization of Xiaobai apricot fruits from diferent producing areas in Xinjiang.
