Analysis of Volatile Compounds in Fruits of Zhenzhuyouxing Apricot by Static Headspace-Gas Chromatography-Mass Spectrometry

Zhenzhuyouxing apricot is rare local variety.The volatile compounds in its fruits were analyzed by static headspace-gas chromatography-mass spectrometry.The results showed that total 22 volatile compounds were isolated and identified,including alcohols,esters,terpenoids,aldehydes,lactones,ketones and hydrocarbons.Hexyl acetate,(Z)-3-hexenyl acetate,(E)-2-hexenyl acetate,β-ionone,(E)-2-hexenal,γ-decalactone and 6-methyl-5-hepten-2-one were the main compounds whose contents accounted for 91.86% of the total compounds.Esters and terpenoids had relatively higher contents as 82.50% and 7.04% respectively,and had 5 and 7 kinds of volatile compounds respectively.The main alcohols and aldehydes were C6 compounds,including 1-hexanol,(E)-2-hexenol,hexanal and(E)-2-hexenal.The detected esters were all acetate ones.
