The Optimized Parameters of Microwave-assisted Extraction of Flavonoids from Plumula Nelumbinis

In order to explore the optimum conditions for microwave-assisted extraction of flavonoids from P lumula nelumbinis and to investigate the effects of microwave power, extraction time and material-liquid ratio on the extraction yield of flavonoids, some processing parameters were optimized by an orthogonal experimental design. It was found that the processing parameters of microwave-assisted extraction affected flavonoids yield in the following order of microwave extraction timemicrowave powermaterial-liquid ratio. The optimal extraction conditions were microwave power 700 W, microwave extraction time 10 min, and material-liquid ratio 2：100 （g：mL）. Under these conditions, the extraction yield of flavonoids from P lumula nelumbinis was 1.8725%. Compared to traditional water extraction method, this optimized method has the advantages of improving yield and shortening extraction time.
