摘要：

为了探讨微波辅助提取莲心中黄酮类物质的工艺条件，研究微波功率、微波提取时间及料液比对莲心黄酮类物质提取效果的影响，通过正交试验设计优化其提取工艺参数。结果表明：影响莲心黄酮类物质提取效果的主次因素顺序为微波提取时间>微波功率>料液比，最佳提取工艺参数为微波功率700 W，微波提取时间10 min，料液比2:100 (g:mL)，在此条件下莲心黄酮类物质提取率为1.8725%；与传统水浸提方法相比，该方法可以提高提取率，缩短提取时间。

Abstract:

The optimum conditions for microwave-assisted extraction of flavonoids from plumula nelumbinis were studied. The effects of microwave power, extraction time, and material-liquid ratio on extraction yield of flavonoids from plumula nelumbinis were investigated. The processing parameters was optimized by orthogonal array design. Results indicated processing parameters of microwave-assisted extraction affected flavonoids yield in the following order of microwave extraction time＞microwave power＞material-liquid ratio. The optimal extraction conditions found 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 plumula nelumbinis was 1.8725%.Compared to traditional water extraction method, this method has the advantages of improving yield and reducing extraction time.
