| 摘 要： | 目的：对啤酒花黄酮类化合物的提取工艺进行优化研究。方法：用单因素试验分别对提取溶剂乙醇含量、料液比、提取温度及提取时间进行研究,在此基础上通过正交试验确定上述4个因素的最佳组合。结果：优化后啤酒花中黄酮的最大提取量为78 mg·g-1。结论：啤酒花黄酮类化合物的适宜提取条件为乙醇含量45%、料液比1∶25、提取温度60 ℃、提取时间90 min。

| Abstract: | OBJECTIVE: To optimize extracting parameters of flavonoids from Humulus lupulus. METHOD: Based on the single factors test on ethanol concentration, material and solvent ratio, extracting temperature and extracting time, orthogonal test was performed and the best combination was confirmed. Result: With the optimized technology, the maximal extracting amount of flavonoids from H. lupulus was 78 mg x g(-1). CONCLUSION: The optimal techniques obtained are 45% ethanol extracting at 60 degrees C with material and solvent ratio 1:25 for 90 min. |
