| Abstract: | Objective:To optimize extraction technology condition of Psoralea corylifolia by supercritical CO2fluid extraction.Method: Single factor test and orthogonal test were used to optimize extraction technology of P.corylifolia with extraction ratio of psoralent and isopsoralent as indexes,extraction temperature,extraction pressure and extraction time were taken as factors.Result: Optimum extraction conditions were as follows:1.5 times the amount of 95% ethanol as entrainer,extraction temperature was 65 ℃,extraction pressure was 20 MPa,extraction time was 2 h.Conclusion: This optimized technology of supercritical CO2 extraction was reasonable and feasible. |
| Keywords: | Psoralea corylifolia psoralent isopsoralent supercritical CO2fluid extraction HPLC |
