OBJECTIVE
To study the extraction of angelica oil by SFE-CO2 (CO2 Supercritical Fluid Extraction).
METHODS
Investigating the influence of the granule size of medical material, extraction temperature, extraction pressure, extraction time, releasing and separating condition on the extraction of angelica oil by the orthogonal design and other methods.
RESULTS
The optimum extraction is as follows: the granule size of medical material, 40 mu; extraction temperature, 40 degrees C; extraction pressure, 25Mpa; extraction time, 2 hours; flow of CO2, 20 L/h; pressure of separation pot I, 8Mpa; temperature of separation pot I, 50 degrees C; pressure of separation pot II, 6Mpa; temperature of separation pot II, 50 degrees C.
CONCLUSION
The optimum extraction has high extraction ratio of angelica oil. The optimum extraction is reasonable and practicable.
