摘要
目的:确定白簕根皮中总黄酮最佳提取工艺。方法:采用微波辅助法提取白簕中的黄酮类化合物,通过单因素试验和正交试验,考察微波提取条件(溶剂、微波辐射时间、微波功率和固液比)对白簕中总黄酮提取率的影响。结果:白簕根皮总黄酮提取最佳工艺为:溶剂50%乙醇、微波辐射时间30s、微波功率320W、固液比为1:20。结论:在此工艺条件下提取,总黄酮得率为30.04mg/g。
Objective:To optimize extraction technology of total flavonoids from the root bark of Acanthopanan trifoliatus.Methods:Total flavonoids were extracted from the root bark of Acanthopanan trifoliatus through a microwave-assisted technique.Effects of operation conditions,such as ethanol content,microwave radiation time,power of microwave oven and the ratio of sample weight to solvent volume were studied by using single factor and orthogonal test.Results:The highest extraction yield can be obtained when extract...
