The method of extracting total flavones in Artemisia sieversiana by ultrasonic wave assistance was introduced. The content of flavone was measured with NaNO2-Al (NO3)3 colorimetry. Based on the single factor and orthogonal experiment, the optimal parameters of total flavone extraction were ethanol concentration of 50%, ultrasonic wave dealing time of 45 min, ultrasonic wave dealing temperature of 50℃ and the ratio of material to solvent of 1:40 (g:mL). The total flavone yield under the optimal condition was 2.18%.
