Abstract：Objective:To study the optimal extraction technology for the volatile components from Dingjiang Hewei plaster by SFE-CO2. Methods:Using the extraction rate and the content of eugenol as the indicators , L9(34) orthogonal design was applied to study the effects of extraction temperature ,extraction pressure and extraction time on Flos Caryophylli,Fructus Amomi,and Rhizoma Zingiberis Recens. Results:Extraction rate of extract was 3.916% and the content of eugenol was 28.688%(mL/g) under the optimal extraction process:extraction temperature at 46℃,extraction pressure at 35 MPa and extraction during being 2.5 hr. Conclu-sion:This extracting technology is simple and efficient ,and this study could provide parameters to optimize the processing technology of Dingjiang Hewei plaster.
