摘要
本文系统地研究了溶剂、浓度、温度、时间对拳卷地钱总黄酮提取的影响,优化了工艺,得到了最佳条件:80%乙醇、74℃、提取2h,提取率达1.90%;并对拳卷地钱总黄酮的提取物进行纯化,选择了溶剂萃取-硅胶柱层析纯化拳卷地钱总黄酮提取物,纯度达95.63%,总收率94.47%。
A method for leaching and purifying the flavones from Marchanfia convoluta was established. The article studied four different solvents to extract flavones from Marchantia convoluta with different concentration, temperature and time. The optimum conditions were: 80 %ethanol at 74℃ extracted for 1 hour, The average yield of flavones from Marchantia convoluta was 1.90 %,
