To study the condition for the extraction of irone in Iris tectorum by supercritical fluids extraction.Conditions for the extraction were studied by a systematic method as guided by the content of irone presented in the extract.The best SFE conditions were: 0.411 mm raw material powder of Iris tectorum, 3% CHCl3 as modifier, temperature of extraction 50 degrees C under the pressure of 25 MPa, with CO2 flow rate of 120L/h, the static extracting time 2 h.
