ABSTRACT
<p><b>OBJECTIVE</b>To study the optimum extraction parameters and components on ant oil from Polyrhachis vicina.</p><p><b>METHOD</b>The optimum condifious for supercritical CO2 fluid extraction (SFE-CO2), were investigated with orthogonal design, GC-MS was applied for analyzing. The components and their contents in the ant oil were analyzed by GC-MS, and the contents of lead, zinc and manganese in the oil were determined by ICP-AES.</p><p><b>RESULT</b>The optimum extraction parameters were achieved, temperature of 50 degrees C, pressure of 30 MPa and time of 2 hours. The extracting yield of the ant volatile oil was 11.4% - 14.3%. 51 Constituents were identified including 9-octadecenoic acid, ethyl oleate, cholesterol, n- Hexadecanoic acid, etc, and the content of various constituents was determined by orea normalization. The oil contained unsaturated fatty acid of 64.6%, lead of 0.80 microg x g(-1), zinc of 0.54 microg x g(-1) and manganese of 0.15 microg x g(-1).</p><p><b>CONCLUSION</b>The method showes advantages including faster and efficient of extraction, good quality and no solvent residues in the oil.</p>
