摘要
目的优选表面活性剂-超声协同提取一点红中总黄酮的工艺条件。方法以总黄酮提取率为指标,采用正交试验优化提取工艺。结果最佳提取工艺参数:1.0%吐温-80,70%乙醇,料液比1∶15,超声提取60min。优化条件下,一点红中总黄酮的提取率为4.63%,明显高于传统提取法。结论采用表面活性剂-超声协同提取一点红中的总黄酮,能提高提取率,可降低生产成本,是一种较理想的提取工艺。
OBJECTIVE To optimize the extraction technology of flavonoids from Emgia sonchifolia（ Linn. ）DC with surfactant-ultrasound extraction. METHODS Orthogonal test were used to study the extraction conditions with extracting rate of flavonoids as indexes. RESULTS The optimal technical conditions as follows： 1.0% tween-80 as solubihzing agent,70% ethanol as extracting solvent, the sound treatment time was 60min. Under this conditions, the than the conventional extraction methods. CONCLUSION rate,lower costs and can be applied muhipurposely. proportion of raw material to solvent was 1 ： 15, the ultraextraction rate reached 4. 63 %, which obviously higher The surfactant-ultrasound method is higher extraction
