摘要：

Subcritical fluid extraction (SFE) technology was used to extract oil from Nib-aria tangutorum seed. The best possible combination of extraction parameters was found using response surface methodology (RSM) in a three-variable, three-level Box-Behnken experimental design (BBD). The optimum extraction parameters were an extraction time of 40 min, an extraction pressure of 0.60 MPa, an extraction temperature of 44 degrees C and a raw material particle size of 0.45 mm. Conventional solvent extraction and supercritical CO2 fluid extraction were comparatively used. The yield of seed oil obtained using SFE was 12.92%, which was similar to or higher than the other methods. The chemical compositions of the seed oil, determined by GC-MS, indicate that its unsaturated fatty acids content was 97%. SFE proved to be an effective technique for extracting oil from N. tangutorum. (C) 2013 Elsevier Ltd. All rights reserved.
