摘要
目的:研究加拿大蓬中总黄酮提取方法及最佳工艺。方法:采用超声提取法,通过单因素试验和正交试验筛选最佳工艺条件。结果:最佳提取条件为60%乙醇、料液比1∶20、60 kW下超声45 m in。得率为31.076 mg/g。结论:该方法提取提取总黄酮快速、简便,可适用于生产中加拿大蓬总黄酮类物质的检测。该方法是提取加拿大蓬总黄酮类物质的有效途径。
Objective： Explore the extraction technology for total flavones from Conyza canadensis （L.） Cronq. Methods： The total flavone were extracted by ultrasonic method. The optimum technological conditions of total flavone extraction were confirmed through single factor test and the orthogonal test. Resuits： The optimum extraction technology conditions were as follows： 60% ethanol, solid -liquid ratio of 1 ： 20, power of ultrasonic 60 kW and time of ultrasonic 45 min. The content of the total flavone of Conyza canadensis （L.） was 31. 076 mg/g. Conclusion： The total flavone extraction by ultrasonic was high - speed and convenient. It is adequate for production of Conyza canadensis （ L. ） total flavone detection. It is an ideal way to extract the flavone of Conyza canadensis （L.）.
