摘要
分别采用水蒸气蒸馏、乙醚浸提、超临界CO2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30～550 u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。
Cinnamomum petrophilum leaves extracts were prepared respectively by steam distillation, ether extraction and supercritical CO2 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 30-550 u, the essential oil produced by steam distillation contained α-limonene, linalool and 2-metbyl- 3-（2-propenyl）phenol besides safrole. The test results showed that steam distillation was the best technology to prepare safrole from C. petrophilum leaves.
