Research of Extraction Process of Total Flavones from Momordica Charantia L.with Microwave

Using Momordica charantia L.as raw material,with the extraction rate of total flavones as evaluation index,the effects of microwave power,liquid-solid ratio,volume fraction of ethanol,particle size of material on extraction rate of total flavones were investigated by single factor experiment.Based on the results obtained,the optimum extraction conditions were determined by orthogonal experiment as follows:microwave power of 500W,liquid-solid ratio of 11∶1(mL∶g),volume fraction of ethanol of 60%,particle size of material of 80 mesh.Under the optimum conditions,the extraction rate of total flavones was 15.576mg·g-1.
