Process Research of the Surfactant-assisted Extraction of Total Flavonoids Extraction from Mulbery Leaves

[Objective] The aim was to study on the technology condition of surfactant-assisted extraction of total flavonoids from mulberry Leaves.[Method] Based on the single factor investigation,orthogonal test was used to optimize the extraction condition.[Result] The optimum extraction conditions were as follows: 1.5% Tween 80 solution,1∶ 40(g/ml) solid-liquid ratio,120 min extraction time,80 ℃extraction temperature,and 2 extraction times.Under this condition,the average extraction rate of total flavonoids was 1.742%.[Conclusion] Surfactant-assisted extraction was a new and efficient extraction method,which could be used for the extraction of total flavonoids.
