Abstract: The extraction of volatile compounds from the fruiting body of Coprinus comatua was carried out using supercritical carbon dioxide fluid extraction technique, and the effects of the pressure and temperature for extraction and separation on extract yield were investigated by 9-run orthogonal array design experiments. The optimal temperature and pressure were 55 ℃ and 20 MPa for extraction and 25 ℃ and 8 MPa for separation. In the extract obtained under these conditions, 25 major components was identified by GC-MS, such as 9,12-octadecadienoic acid (52.67%), octadecenoic acid (27.77%) and hexadecenoic acid (13.66%).

Key words: Coprinus comatua, volatile flavor compounds, supercritical CO2 fluid extraction, gas chromatographymass spectrometry
