| 摘 要： | 分别采用水蒸气蒸馏、乙醚浸提、超临界CO_2萃取从岩桂叶中提取得含黄樟油素的精油(浸膏),产品得率分别为2.09%、3.14%和3.75%,通过气相色谱法测得其黄樟油素GC含量依次为94.9%、36.1%和15.9%.采用气相色谱 - 质谱联用法对气相色谱法进行了确证,测得水蒸气蒸馏法制备的精油中分子质量在30 ～ 550u范围的物质,除黄樟油素外,还含有α - 柠檬烯、芳樟醇、2 - 甲基 - 3 - (2 - 丙烯基)苯酚.实验结果表明,水蒸气蒸馏法是制备岩桂叶精油的最好方法. |

| Abstract: | Cinnamomum petrophilum leaves extracts were prepared respectively by steam distillation, ether extraction and supercritical CO_2 extraction, to obtain product yields of 2.09%, 3.14% and 3.75% respectively. Safrole contents of the extracts were 94.9%, 36.1% and 15.9%, respectively, analyzed by GC, which was confirmed by GC-MS. For the substances of molecular weight between 30 - 550u, the essential oil produced by steam distillation contained α-limonene, linalool and 2-methyl-3-(2-propenyl)phenol besides safrole. The test results showed that steam distillation was the best technology to prepare safrole from C.petrophilum leaves. |
