摘要
采用微波提取法提取槲蕨根茎中的黄酮类物质,并用比色法测定提取率。通过单因素实验和正交试验得出结论,最佳提取条件为:乙醇浓度40%、料液比1:20(g/mL)、微波功率325 W、提取时间40 s,在此条件下提取率为1.73%。其中微波功率对提取率的影响最大,与传统溶剂浸提法相比,微波提取法具有明显优势。
The experiment extracted flavonoids in rhizome of Drynaria fortunei by microwave extraction,and determined the extraction rate through colorimetry.Through the single factor experiment and orthogonal method,the optimum extraction conditions were as follows：ethanol concentration was 40%,solid-liquid ratio was 1：20（g/mL）,microwave power was 325 W,extraction time was 40 s.Under these conditions,the extraction rate reached 1.73%.In all condtions,microwave power has the most significant effect on extraction rate.Microwave extraction has obvious advantages in comparison with traditional sovent refluxing method.
