| Abstract: | The technological conditions of extracting Seabuckthorn Oil with the supercritical -CO2 extraction from Seabuckthorn seeds were studied. Factors affecting extraction yield, such as extraction temperature, pressure, time, graininess, and weight faction were discussed. The single factor experiment and orthogonal test of supercritical CO2 extraction were carried out and optimal conditions were obtained as follows: pressure 35Mpa, temperature 40℃, time 2.5h and graininess 40mesh. Under such conditions, the extraction rate of Seabuckthorn Oil was 7.68%。 |
