| Abstract:
The compositions of the volatiles from Artabotrys hexapetalus flowers were investigated. These volatiles were obtained by simple headspace-solvent trapping technique with dichloromethane as the trapping solvent. The investigation was performed in combination of gas chromatography-mass spectrometry (EI and PCI) and retention indices. Seventeen components were identified with ethyl acetate (47.3%), ethyl isobutanoate (9.2%), isobutyl acetate (26.8%) and ethyl butanoate (9.7%) as the major components. The extract was also compared with those obtained by solid-phase microextraction (SPME), solvent extraction and hydrodistillation. The odor of the solution from this technique was similar to that of the fresh flowers and differed from that obtained by solvent extraction and hydrodistillation. | |
