| 摘 要： | 采用水蒸气蒸馏法（HD）、微波辅助-水蒸气蒸馏法（MAHD）和微波无溶剂提取法（SFME）提取樟树落叶挥发油,用气相色谱-质谱及峰面积归一化法对挥发油成分进行分析鉴定.实验结果表明,3种方法提取的挥发油提取率接近,水蒸气蒸馏法为0.98％,微波辅助-水蒸气蒸馏法为1.12％,微波无溶剂提取法则为1.04％.3种方法提取的挥发油共鉴定出29种化合物,单萜类氧化物和倍半萜氧化物为挥发油的主要成分;HD所得挥发油中香樟醇、桉树叶醇、樟脑和α-松油醇的质量分数分别为25.58％、21.26％、16.79％和11.19％,MAHD为26.29％、28.72％、15.64％和10.16％,SFM为17.74％、17.74％、17.74％和12.46％.不同方法提取的樟树落叶挥发油提取率及成分总体相近,但也存在一定差异,这为进一步开发利用樟树落叶提供了一定的实验依据.

| Abstract: | The volatile oil of the fallen leaves of Cinnamomum Camphora were extracted by traditional hydro-distillation（HD）,microwave assisted hydro-distillation （MAHD）and solvent-free microwave extraction （SFME）.The chemical constituents were separated and identified by gas chromatographymass spectrometry,the relative contents were analyzed by peak area normalization.The results show that there is no significant difference in the yield of volatile oils obtained by the three kinds of extraction methods; the yield of HD,MAHD,SFME is 0.98％,1.12％ and 1.04％.29 compounds were identified in the volatile oil,mainly including monoterpene oxides and terpene oxides.Camphor alcohol,eudesmol,camphor,alpha-terpineol are the main component in the volatile oil.The contents of these component are 25.58％,21.26％,16.79％ and 11.19％ by HD,26.29％,28.72％,15.64％ and 10.16％ byMAHD,and 17.74％,17.74％,17.74％ and 12.46％ by SFME.It is useful for further development of the fallen leaves of Cinnamomum camphora. |
