Abstract

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 rinding shell may improve extraction rates of Litsea cubeba kernel oil.

Key words: Litsea cubeba kernel oil, SCDE(supercritical carbon dioxide extraction)
