目的：优化叶下珠多酚的提取工艺。方法：以叶下珠为原料,通过单因素试验与正交试验L9（3^4）,对叶下珠总多酚的提取工艺进行优化。结果：叶下珠总多酚提取最佳工艺为乙醇体积分数为60%,料液比为1∶20（g/mL）,提取时间为70 min,温度为40℃。结论：本研究确定的优化工艺叶下珠总多酚得率最高,工艺便捷,结果稳定可靠。

Objective：To optimize the extracting process of polyphenol from Phyllanthus urinaria L..Methods：To optimize the extraction process by using single-factor test and orthogonal test L9（3^4）.Results：The preferred process of total polyphenol extraction was that the volume fraction of ethanol was 60%,the ratio of material to solution was 1∶20 g/mL,the extracting time was70 min,and the temperature was 40 ℃.Conclusion：The highest total polyphenol yield is obtained by this method.The process is co...
