Objective: To optimize the conditions of supercritical fluid extraction(SFE) for curcumin in Curcuma longa. Method: Optimum extraction conditions were studied by orthogonal tests. The extracts were analyzed by HPLC. Result: The optimal extraction conditions were pressure 25 MPa, temperature 55 degreeC, static time 4 h, dynamic time 5 h, flow rate of CO2 3.5 L.min-1, co-solvent ethanol 30% (mL.g-1). Conclusion: It is feasible to extract curcumin by SFE.
