| Abstract: | The technics of extracting angelica root oil by supercritical fluid extraction is studied. The conditions of the extraction technology are optimized by orthogonal experiments. The results show that the best condition is 30 MPa of the extraction pressure, 50 ℃ of the extraction temperature, 9 kg/h of the flow quantity of CO2 and extracting for 3 hours. Under this condition, the yield of angelica root oil is 2.47 %. |
