Objective: To optimize supercritical CO2 fluid extraction(CO2-SFE) conditions of four medicinal herbs in Shufushuang sprays including Cnidium monnieri
et al. Method: With the content of ostho1e and total extraction yield as comprehensive evaluation index
the content of osthole was determined by HPLC
CO2-SFE of four medicinal herbs in Shufushuang sprays was optimized by orthogonal design with extraction pressure
extraction temperature and the separating kettleⅠ temperature as factors. Result: Extraction pressure and temperature had significant effects on CO2-SFE
whereas the separating kettleⅠ temperature had no significant effects.Optimum CO2-SFE technology was A2B1C1
extraction pressure 30 MPa
extraction temperature 50 ℃
the separating kettleⅠ temperature 50 ℃. Conclusion: Optimized extraction technology of volatile oil was stable and feasible
