Abstract:

Volatile components in 4 kinds of monofloral hoeny from oleaster, sunflower, rape and cotton were analyzed by solid phase microextraction (SPME) followed by gas chromatography and mass spetrometry (GC-MS). A total of 144 volatile compounds were identified in 39 kinds of honey. Linalool, 2-(1,1-dimethylethyl)-cyclohexanol and diphene were the characteristic compounds in oleaster honey; cedrol was the characteristic compound in rape honey; 4-terpineol, 9-(3,3-dimethylepoxyethyl- 2-alkyl)-2,7-dimethyl-nona-2,6-enol, 2-camphene, 1-methyl-4-isopropenyl benzene, myrtenol, α,α,4-trimethyl- 2,4-cyclohexadiene-1-methanol andα-terpineol were the characteristic compounds in sunflower honey; 3-phenyl acrolein and 3-phenyl-2-allyl alcohol were the characteristic compounds in cotton honey.

Key words: solid-phase microextraction (SPME), monofloral honey, volatile compounds, gas chromatography and mass spetrometry (GC-MS)
