第46卷 第3期 广 西 林 业 科 学 Vol.46 No.3 2017年9 月 GuangxiForestryScience Sep.2017 文章编号:1006-1126-2017 (2) -0315-04 油樟型樟树精油的成分分析 杨素华,安家成,陆顺忠,邱 米,苏骊华,党中广 (广西壮族自治区林业科学研究院,南宁 530002) 摘 要:以油樟型樟树 (Cinnamomum camphora )根为研究对象,采用水蒸气蒸馏法提取精油,并用气相色谱仪和气- 质联用仪对精油进行分析。结果发现,油樟型樟树根的平均得油率为3.10% ;从根精油中鉴定出相对含量≥0.16%的组 分27 种,占精油总量的98.79% ;相对含量>1% 的组分有13种,分别为1,8-桉叶油素 (27.10% )、樟脑 (23.35% )、 黄樟油素 (11.96% )、α-松油醇 (10.70% )、4-松油醇 (5.26% )、石竹烯 (3.21% )、愈创木醇 (2.44% )、α-蒎烯 (1.45% )、甘香烯 (1.31% )、香桧烯 (1.30% )、龙脑 (1.21% )、γ-松油烯 (1.17% )、肉豆蔻醚 (1.09% ),占精油总量 的91.55% ;相对含量>10% 的组分有4 种,分别为1,8-桉叶油素、樟脑、黄樟油素、α-松油醇,占精油总量的 73.11%。油樟型樟树根精油中有较多的活性成分,具有较高的应用价值。 关键词:樟树;油樟型;精油;成分分析 中图分类号:S792.23 文献标识码:A Analysis on Components of Essential Oils in Cineol Type of Cinnamomum camphora YANG Su-hua ,AN Jia-cheng ,LU Shun-zhong ,QIU Mi ,SU Li-hua ,DANG Zhong-guang (Guangxi Forestry Research Institute,Nanning 530002,China) Abstract: Taking cineol type of Cinnamomum camphora as the research object ,essential oils from roots were extracted by steam distillation method and were analyzed by GC and GC-MS. The results showed that the aver⁃ age essential oil yield of root was 3.10% ,and twenty-seven components from the root essential oils were identi⁃ fied ,which relative contents were greater than 0.16% ,and accounted for 98.79% of the total contents. Thir⁃ teen components with relative contents greater than 1% were identified from the root essential oils ,and they were eucalyptol ,bornanone ,safrole ,α-terpineol ,4-carvomenthenol ,caryophyllene ,guaiol ,α-pi⁃ nene ,elixene ,sabinene ,borneol ,γ-terpinene and myristicin with 27.10% ,23.35% ,11.96% , 10.70% ,5.26% ,3.21% ,2.44% ,1.45% ,1
