Moringa leaves were used as raw materials, ethanol and ammonium sulfate were used to construct a aqueous two-phase system to extract the flavonoids from Moringa leaves. The solid-liquid ratio, ethanol content, ultrasonic extraction time, and ultrasonic extraction temperature were selected as single factors, and the extraction process of flavonoids was optimized through single-factor experiments and orthogonal experiments. The optimal process was: 1:110 of solid-liquid ratio, 45 % of ethanol concentration, 15 minutes of ultrasonic extraction time, 70 °C of ultrasonic extraction temperature. Under this condition, the extraction rate of Moringa leaf flavonoids reached 8.37 %.
