| Abstract: | The effect of different parameters such as extraction time,resolution temperature and extraction pressure on the supercritical carbon dioxide extraction of solanesol was investigated.With pretreatment such as saponification,the optimal extraction conditions were determined according to orthogonal experiments as entrainer 90% ethanol(volume fraction),extraction pressure 35 MPa,extraction temperature 50 ℃ and resolution temperature 40 ℃.After extraction for 3 h,mass fraction of the solanesol was 40.14%,and extraction rate was as high as 98.53%. |
