| 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700W,微波提取时间10min,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: | 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 time>microwave power>material-liqu... |
