| Abstract: | To discuss the extraction technology ofStellera chamaejasme root oil by supercritical fluid in this study. The optimal technological conditions including the supercritical CO2 flow, extraction time, extraction pressure, extraction temperature, separation temperature and separation pressure were determined by the single factor experiment and the orthogonal experiment. The sequences of the factors affecting the extraction are： extraction pressure separation pressure extraction temperature separation temperature. The optimum extracting conditions are as follows： supercritical CO2 flow 21 L/h, extraction time 100 min, extraction pressure 30 MPa, extraction temperature 46℃, separation temperature 45℃, separation pressure 5.5 Mpa. Under the above process conditions, the extraction yield ofS. chamaejasme root oil reached at 3.57%. |
