[Supercritical carbon dioxide extraction of essential oil from Cinnamomum migao H. W. Li]
1School of Chemical Engineering and Technology, Tianjin University, Tianjin 300072.
Abstract:
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.
