[The process study on the extraction of irone by supercritical fuilds extraction].
OBJECTIVE
To study the condition for the extraction of irone in Iris tectorum by supercritical fluids extraction.


METHODS
Conditions for the extraction were studied by a systematic method as guided by the content of irone presented in the extract.


RESULTS
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.
