| Abstract: | The tobacco leaves were taken as raw materials, and the process for extracting solanesol from tobacco leaves with Supereritical CO2 was studied. The factors affecting the quality yield of solanesol were determined. The coptimum conditions were as follows： extraction pressure 25-35 MPa, extraction temperature 35 -45℃, the flow - rate of CO2 2.0 - 3.0 L·min^-1, 85 % ethanol as the entrainer, the flow - rate of the entrainer 0.25 - 0.35 mL·min^-1and extraction time under 2 h. |
