| Abstract: | 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 showthat 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. |
