摘 要:The essential oil was extracted from fresh leaf and defoliation of Bischofia polycarpa(Lévl.) Airy Shaw using steam distillation,and the chemical components and relative content of essential oil were analyzed by GC-MS and peak area normalization.The results show that the yields of crude extracts of essential oil from fresh leaf and defoliation are 0.114% and 0.105% respectively,and 114 and 15 peaks have been obtained respectively.Forty-seven compounds have been identified from the essential oil of fresh leaf,and the main compounds are camphor,2-hexenoic acid,heptacosane,dibutylphthalate,diethyladipate,2,6,10-trimethyl tetradecaneanddiisobutyladipatewith relativecontents of 10.416%,8.078%,7.627%,7.463%,5.171%,4.411% and 4.144%,respectively.Fourteen compounds have been identified from the essential oil of defoliation,and the main compounds are camphor,2-carboxymethyl-3-n-hexylmaleic acid anhydride and eucalyptol with relative contents of 33.070%,12.670% and 8.620%,respectively.The relative content of camphor in essential oil from fresh leaf and defoliation is the highest.The essential oil was extracted from fresh leaf and defoliation of Bischofia polycarpa(Lévl.)
