| Abstract: | An isolation technology of Litsea cubeba kernel oil in a dynamic supercritical fluid extraction system was described. Factors influencing extraction yield were discussed. By orthogonal test, the optimum technological conditions were：extraction temperature 45 ℃, pressure 25 MPa, flow rate of carbon dioxide 220 L/h and extraction time 80 min. The yield of extraction was 84.5 %. It is proved that adding the solvent and finding shell may improve extraction rates of Litsea cubeba kernel oil. |
