Abstract: To explore the optimal plan of extracting total flavone from mulberry leaves through the method of supercritical carbon dioxide, this research utilized supercritical carbon dioxide extraction technology and applies response surface method to examine the influence of extraction pressure, extraction temperature, extraction time and flow velocity of entrainer absolute ethyl alcohol on yield of total flavone in mulberry leaves, and selected the optimal technology that mulberry leaves flavonoids extract using supercritical fluid extraction device. The results indicated that, the optimal extraction condition of response surface method was as follows: pressure in optimal extraction plan was 26 MPa, temperature was 50℃, time was 3 hours, and flow velocity was 2.5 mL/min. The predicted total flavone yield under optimal condition was 6.21%±0.05%.

Key words: mulberry, supercritical carbon dioxide extraction, flavonoid yield, corresponding method of curved surface
