Abstract:

The extraction of Sapium sebiferum Roxb epidermis oil was carried out with supercritical fluid carbon dioxide technique, and the effects of extraction pressure, temperature and CO2 flow rate on extraction rate of Sapium sebiferum Roxb epidermis oil were investigated through orthogonal design.The results showed that the optimal extraction pressure, temperature, CO2 flow rate and time for the maximum extraction rate are 40 MPa, 36 ℃, 20 L/h and 1 h, respectively. Meanwhile the components of Sapium sebiferum Roxb epidermis oil were analyzed with gas chromatography (GC).

Key words: supercritical CO2 fluid, extraction, Sapium sebiferum Roxb epidermis oil, GC analysis
