Essential oil from Cinnamomum migao H. W. Li. was extracted by supercritical fluid extraction (SFE) using carbon dioxide and a two-stage fractional separation system. The experiment was carried out under 306K-333K and 10-30 MPa. The influence of the process parameters were discussed. The GC-MS method was applied to analyze the components of these oils obtained by SFE. The result by SFE was better than that by stream distillation.
米槁（Cinnamomum migao H. W. Li.）精油采用超临界流体萃取（SFE）法，以二氧化碳为萃取剂，通过两级分馏分离系统进行萃取。实验在306K - 333K和10 - 30MPa条件下进行。讨论了工艺参数的影响。采用气相色谱 - 质谱联用（GC - MS）法分析通过超临界流体萃取得到的这些精油的成分。超临界流体萃取的结果优于水蒸气蒸馏法。
