| Abstract: | The extraction of total flavones from eichhornia crassipes by microwave extraction using response surface analysis is researched to optimize the experimental conditions.Based on single factor test,Box-Benhnken Design is applied to investigate the effects of microwave power,microwave extraction time and liquid-solid ratio on the extraction rate of total flavones from eichhornia crassipes.Quadratic regression equation between the extraction rate of total flavones and the factors is established,and variance analysis showed that the model is very significant.The optimal extraction conditions are determined as follows: the microwave power at 410 W,the extraction time at 6 min and the liquid-solid ratio at 41∶1 mL·g-1.In this case,the extraction rate of total flavones from eichhornia crassipes sample reaches 7.630 mg·g-1. |
