| Abstract: | In order to investigate the composition of characteristic aroma of Toona sinensis (A.Juss.) Roem.and its change under different storage conditions,aroma compounds were condensed by headspace solid-phase microextraction (HS- - SPME).Two of 43 compounds,named A and B,which had characteristic aroma of T.sinensis,were identified by gas chromatography-olfactometry (GC- - O) and GC-olfactometry-mass spectrometer (GC- - O- - MS).They were shown to be sulfur-containing by GC- - flame photometric detector (GC- - FPD... |
