Using supercritical CO2 extraction of general flavone compounds in the leaves of Acantho?panax trifoliatus, by single factor test and orthogonal test, the supercritical extraction conditions (pressure, tem?perature, time and CO2 flow rate) of the effects of general flavone are studied. The experimental results show that the optimum extraction conditions: 20 MPa extraction pressure, extraction temperature 35℃, 1 hour ex?traction time, CO2 flow 20 l/h. Validation experiments show that the flavonoids extraction in Acanthopanax trifo?liatus leaves as:2.940 mg/g, to prove that the conditions for the optimum extraction conditions.
