摘要
水蒸气蒸馏法从芳樟醇型樟树的枝、叶中提取精油,测定其含油率,并用气相色谱仪和气-质联用对精油进行了定性和定量分析。研究发现,芳樟醇型樟树不同部位的精油含量及精油的化学成分含量有较大差异,树叶(嫩叶和老叶混合样,下同)中精油质量分数(1.39%)高于树枝(0.54%);树叶精油中芳樟醇质量分数(89.59%)高于树枝(74.49%);树叶精油中樟脑质量分数(0.61%)低于树枝(4.34%);树叶精油10月份采集的品质(芳樟醇92.69%、樟脑0.40%)优于7月份采集的(芳樟醇86.49%、樟脑0.82%)。
Essential oil from stem and leaf （ samples of mixed leaves and old leaves） of linalool-type Cinnamomum camphora （Linn.） Presl was extracted respectively by steam distillation method. The essential oils were analyzed with gas chromatography and GC-MS-DS quantitatively and qualitatively. The results show that content and chemical compositions of essential oil from stem and leaf of linalool-type C. camphora have great difference. The mass fraction of essential oil in leaves （ 1.39 % ） is higher than in stem （0.54 % ） ; The mass fraction of linalool in leaf essential oil （89.59 % ） is higher than in stem （74.49 % ） ; The mass fraction of camphor in leaf essential oil （0.61% ） is lower than in stem （4.34 % ） ; The quality of leaf essential oil collected in October （ linalool 92.69 %, camphor 0.40 % ） is superior to leaves collected in July linalool 86.49 %, camphor 0.82%）.
