Microwave-assisted Extraction of Total Flavonoids from the Flower of Gossampinus malabarica(DC.) Merr


  [Objective]To confirm the optimum extraction conditions for total flavonoids from the flower of Gossampinus malabarica(DC.) Merr.[Method] The technological conditions of microwave-assisted extraction for total flavonoids were investigated by the single factor test and orthogonal test.[Result] The optimum conditions of microwave-assisted extraction were as follows:microwave extraction time of 100 s,microwave power of 240 W,ethanol concentration of 60%(V/V,the same as following) and solid-liquid ratio of 1:40,under which the yield of total flavoniods from the flower of Gossampinus malabarica(DC.) Merr.was 4.79%.The yield of total flavonoids extracted with the conventional method was 4.07%.[Conclusion]The Microwave-assisted extraction was superior to the conventional method,and this study would provide experimental and theoretical evidence for the utilization of Gossampinus malabarica(DC.) Merr..……
