Volatiles of different Chaenomeles sinensis cultivars in Shandong Province were investigated by means of HS-SPME coupled to GC/MS,and the fruit aroma of different cultivars was studied.Result showed that the 161 volatiles,belonging to 7 categories,were identified.Esters,alcohols and aldehydes are the major constituents.Ethyl alcohol,3-methyl-4-oxo-pentanoic acid,acetic acid butyl ester,2-methyl-butanoic acid ethyl ester,diethyl phthalate,(E,E)-2,4-Decadienal are the main volatiles from the 10 cultivars.Ethyl alcohol and(E,E)-2,4-Decadienal were the primary volatiles.Some unique and high relative content volatiles,playing an important role in the formation of specific aroma of different Chaenomeles sinensis cultivars,were detected from most cultivars.There were significant difference between volatile,relative contents and aromatic categories.
