| Abstract: | Total flavones of Suaeda australis leaves （LFSA） in Quanzhou Bay Wetland were extracted by the microwave-alkali water method. Taking the extraction rate of total flavone determined by ultraviolet spectrophotometry as an inspecting index, the microwave-alkali water optimization of water pH, microwave power,ratio of liquid to material and time of microwave treatment microwave- alkali water extraction process were achieved by single experiment and L16 （45 ） orthogonal test. The results showed that alkali water pH has significant effect on the extraction rate of total flavonoids.the optimum extraction conditions of microwave-alkali water method are as follows, the alkali water pH value being 13 ,the microwave power as 600 wattage,ratio of liquid to material being 70, microwave treatment time as 9 minute and making the extraction for one time. Under such condition, the extraction rate of total flavones is 4.87 %. |
