The head space-solid phase micro extraction method was used to extract the flavor compositions from six varieties of Zizyphus jujuba. The extracted flavor compositions were analyzed by gas chromagraphymass spectrometry method. And principal component analysis and correlation analysis was adopted to investigate their flavor compositions. The results indicated that the number of flavor compositions identified in them was 34 that including acids(12 kinds),esters(2 kinds),hydrocarbons(6 kinds),alcohols(2 kinds)...
