| Abstract: | Supercritical CO2 fluid was used to extract Solanesol from Tobacco Leaves. The quality yield of Solanesol was used as the evaluation index and extraction temperature、extraction pressure、the flow-rate of CO2、the concentration of entrainer and the flow rate of entrainer as affecting factors,the optimal extraction process was determined by orthogonal experiments. The optimum extraction process was set as follows：extraction temperature at 40 ℃,extraction pressure under 35 MPa,extraction time 2 h,absolute ethyl alcohol as the entrainer,the flow rate of entrainer was 0. 3 mL-1·min-1,in this experimental condition,the average quality yield of Solanesol was 0.8288%. |
