[Studies on the supercritical CO2 fluid extraction and separation of psoralen, isopsoralen and fatty oils from Psoralea corylifolia].
Opimum extraction conditions were studied by supercritical carbon dioxide fluid extraction technology and orthogonal tests. Crystal of psoralen can be achieved directly from the extractives. Magnified experiments were carried out. The chemical constituents of fatty oils were analyzed by GC-MS. The result shows that the optimum conditions are: extraction pressure 27 MPa, extraction temperature 70 degrees C; seperation pressure 9 MPa, seperation temperature 60 degrees C. Six components such as oleic acid, linoleic acid etc. were identified in the fatty oils.
