Abstract:
OBJECTIVETo optimize the conditions of supercritical fluid extraction (SFE) for curcumin in Curcuma longa.
METHODOptimum extraction conditions were studied by orthogonal tests. The extracts were analyzed by HPLC.
RESULTThe optimal extraction conditions were pressure 25 MPa, temperature 55 degrees C, static time 4 h, dynamic time 5 h, flow rate of CO2 3.5 L x min(-1), co-solvent ethanol 30% (mL x g(-1)).
CONCLUSIONIt is feasible to extract curcumin by SFE.
