    Abstract：ObjectiveTo study the optimal technology of supercritical- CO2 fluid extraction(SFE-CO2) on Combined Spicebush Root . MethodsContent of Linderane was used as index to evaluate the technologies based on orthogonal design , in which 4 factors considered were extraction temperature and pressure , separation temperature and pressure . ResultsThe optimum extraction conditions is : extraction pressure = 20MPa , temperature = 35℃ ; separation pressure = 8MPa , temperature = 55℃ ; extraction time = 4 hours , and CO2 flow rate = 20 L/h .ConclusionSupercritical fluids extraction method is simple for the activities of Combined Spicebush Root , and useful for the large scale production . ......
