摘要
目的:优化乌饭树树叶中总黄酮的超声提取工艺。方法:采用单因素试验和正交设计,以总黄酮的含量为指标,以提取溶剂浓度、料液比、提取时间、提取次数为试验因素,优化乌饭树树叶中总黄酮的超声提取工艺。结果:优化试验方案所得乌饭树树叶中总黄酮最佳提取工艺为:70%乙醇,料液比为1∶40,提取时间30 min,提取次数2次。结论:该提取工艺稳定、可行,研究结果可为改进现有乌饭树树叶总黄酮的提取工艺提供有益参考。
Objective：To optimize the ultrasound-assisted extraction process of total flavonoids in Vaccinium bracteatum Thunb. leaves. Methods：The single factor test and orthogonal test were adopted with the content of total flavonoids as the index, and the ultra-sound-assisted extraction was optimized with the concentration of solvent, extracting time, ratio of raw material to liquid and extraction times as the factors. Results：The optimal extraction conditions were 70% ethanol with 40-fold volume, extracting 2 times with 30 mi-nutes per time. Conclusion：The extraction process is stable and feasible, and all the results are useful references for the extraction process improvement.
