摘要
研究利用超声波辅助提取荷叶中多酚类化合物的最佳条件,考察了超声作用时间、提取次数、料液比和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,确定其优化工艺条件为:乙醇体积分数60%,作用时间15 m in,料液比为1:14,提取次数为4次。
The optimal condition of polyphenol extraction from lotus leaf by ultrasonic were studied. The effects of action time, ratio of raw materials, solution and extraction times on extraction rate of polyphenol were in-vestigated. The best technical conditions for polyphenol extraction was obtained through orthogonal experiments as follows： ratio of raw materials and solution of 1：14, four extraction times, 60% alcohol and extraction period of 15 min.
