Analysis of Volatile Components from Toona sinensis(A Juss.) Roem Buds and Leaves by Headspace-Solid Phase Micro-extraction Gas Chromatography-Mass Spectrometry

The volatile components from Toona sinensis(A Juss.) Roem buds and leaves were analyzed by Headspace-Solid Phase Microextraction Gas Chromatography-Mass Spectrometry.26 kinds of volatile components were identified in Toona sinensis(A Juss.) Roem buds,which relative mass fraction account for 74.86%,the major volatile components from Toona sinensis(A Juss.) Roem buds were β-caryophyllene(mass fraction,same as below 10.12%),(2-aziridinylethyl)amine(10.09%),propanoic,(2-aminooxy)-(10.03%),β-bergamotene(8.78%),eudesma-4(14),11-diene(6.59%),α-cubebene(3.02%),α-cedrene(2.88%),ocimene(2.69%),8-isopropenyl-1,5-dimethyl-1,5-cyclodecadiene(2.36%),2-hydroxyethylhydrazine(2.10%),cedryl propyl ether(2.07%),acetaldehyde,hydroxy-(1.88%),cyclodecanol(1.63%),fenchol,exo-(1.54%),1,3,8-p-menthatriene(1.46%),α-curcumene(1.18%);46 kinds of volatile components were identified in Toona sinensis(A Juss.) Roem leaves,which relative mass fraction account for 91.2%,the major volatile components from Toona sinensis(A Juss.) Roem leaves were β-caryophyllene(46.87%),(E)-2-hexenal(5.29%),α-caryophyllene(4.12%),8-isopropenyl-1,5-dimethyl-1,5-cyclodecadiene(3.96%),β-bergamotene(3.48%),eudesma-4(14),11-diene(3.37%),α-cubebene(3.23%),β-bourbonene(2.41%),(2-aziridinylethyl)amine(2.23%),α-farnesene(1.42%),iso-caryophyllene(1.22%),β-terpinene(1.03%).
