摘要
目的:优化选择桑叶中总黄酮的最佳超声提取工艺。方法:采用正交实验法,以提取液中总黄酮含量为考察指标,对影响总黄酮提取工艺的因素进行了研究。结果:实验设计三因素中超声时间有显著影响。结论:桑叶总黄酮的最佳超声提取工艺为用20倍量50%乙醇,提取30min。
Objective： to establish the optimal conditions for ultrasonic extraction of total flavonoids from Mulberry leaves. Methods： The conditions for the extraction were studied by the orthogonal experimental design as guided by the content of total flavonoids in the extract. Results： a significant effect, the time of ultrasonic extraction, was observed. Conclusion： Using total flavonoicls as a detecting index, the optimum conditions are that the concentration of alcohol is 50%, the rate of solvent to raw materials is 20 times and the ultrasonic time is 30 min.
