Abstract:
Objective To study the optimum parameters of the supercritical CO2 fluid extraction of Polyrhachis vicina Roger and chemical constituents of ant oil. Methods The experiments were designed with the uniform design. Three factors are extraction pressure, temperature and time. GC-MS was applied for analyzising. Results The optimum condition was obtained:the extraction pressure is 36 MPa, the temperature of extraction is 40 ℃ and extraction time is 50min. 45 components were identified from 60 chromatographic peaks. The main chemical constituents were (Z)-9-octadecenoicacid (48.278%), hexadecanoicacid (17.574%), (Z)-9-hexadecenoi (4.912%), cholesterol (2.957%). There are some linear paraffin in ant oil. Conclusion This method can extract the ant oil from Polyrhachis vicina Roger quickly and efficiently. This experiment provide foundation for exploitation and utilization of ant resource.
