摘要
目的:研究利用微波辅助提取荷叶中多酚类化合物的最佳条件。方法:考察微波作用时间、微波功率、料液比及乙醇体积分数等因素对荷叶多酚提取率的影响,并在单因素实验的基础上进行正交实验。结果:最佳工艺条件为乙醇体积分数20%、微波作用时间150s、料液比为1∶60、微波功率为300W。
Objective： The optimal condition of polyphenol extraction from lotus leaf by microwave was studied. Methods： The effects of single fectors, such as microwave treation time, microwave power, ratio of raw materials to liquid, percent of ethanol volume was investigated. Results： The best technical conditions for polyphenol extraction was obtained through orthogonal experiments as follows： ratio of raw materials and solution of 1：60, microwave power as 300 W, 20% alcohol and extraction period of 150 s.
