Abstract:

A recent study found that the aroma quality of geranium oil could be identified by gas chromatography-mass spectroscopy-olfactory (GC-MS/O).This study aimed to describe the aroma profiles and evaluate the aroma image.Twenty-four key aroma components of seven kinds of geranium oils were identified with intensity method and mass spectrometry library,which were geranium aroma including geraniol,β-citronellol,camphorin methyl ester;Rose aroma including linalool,rose ether,ethyl geranyl ether,geranyl acetate,γ-itranolene;Green aroma including trimethyl cyclohexenol,trans-oxide linalool(furan type),phenyl ethanol,L-menthone,isomenthone,L-menthole;Fruity aroma including acetaldehyde diethyl acetal,isoamyl alcohol,α-pinene,1,1-diethoxy-3-methylbutane,limetol,β-pinene,limonene;Preserved fruit aroma including cis-oxide linalool (furan type),geranyl formate,α-itranolene.

Key words: geranium oil, gas chromatography-mass spectroscopy-olfactory, key aroma components, aroma profile
