| Abstract: | The extraction process of Trichosanthes kirilowii Maxim seed oil by supercritical CO2 extraction was studied.The effect of the factors on extracting ratio such as grinding fineness of Trichosanthes kirilowii Maxim seed,extracting temperature,extracting pressure and extracting time were investigated by using single factor test and orthogonal test.The results showed that the optimal conditions for the extraction were 90 mesh,50 ℃,30 MPa and 3.0 h.Under such conditions,the extracting ratio was 39.6%. |
