Supercritical CO2 fluid exrtaction was applied to ficus pumila L. seeds extraction. The effect factories on the supercritical exrtaction were wokred out via single factor experiments, and the operative parameters were optimized by use orthogonal experiment. The Oil with SCFE-CO2 under optimal conditions was compared to curde oil extracted by petroleum ether; Most of constituents of the absolutes were analyzed uesing GC-MS. A comparative study of flower concretes exctracted by supercritical CO2 and p...
