Single factor and orthogonal experimental tests were used to determine the comprehensive effects on extraction ratio of total flavonoids by extraction,temperature,time,amount of alcohol solvent by using the extraction ratio of flavonoids as the index to study the optimal supercrnical CO2 extraction conditions of navonoids from mulberry leaves.The optimal conditions of the extraction could be mentioned as the extraction pressure was 30MPa,the extraction temperature was 40 ℃,the extraction time was 3.0 h,the amount of alcohol solvent was 4.0 mL/g,the extraction ratio of total flavonoids was 3.2%. The research showed that the extraction ratio of supercritical extraction was much higher than that of supersonic extraction,and the former was fit to extract total flavonoids in large-scale.
