Method for extracting total flavonoids from gordon euryale seed shells

The invention belongs to the technical field of total flavone extraction, and particularly relates to a method for extracting total flavone from gordon euryale seed shells. According to the method, the total flavonoids are extracted by treating the gordon euryale seed shells with the eutectic solvent in cooperation with the ultrasonic waves, the extraction amount of the total flavonoids in the gordon euryale seed shells is effectively increased, and the yield of the total flavonoids is increased. The result of the embodiment shows that the yield of the total flavonoids in the gordon euryale seed shells can reach 7.6% by optimizing the types of the eutectic solvents, the component molar ratio, the water content, the liquid-material ratio of the total system and the ultrasonic power and time in the process of treating the gordon euryale seed shells in cooperation with the eutectic solvents and the ultrasonic waves. 本发明属于总黄酮提取技术领域，具体涉及一种提取芡实壳总黄酮的方法。本发明通过以低共熔溶剂协同超声波处理芡实壳提取总黄酮，有效增加了芡实壳总黄酮的提取量，提高了总黄酮的得率。实施例结果表明，本发明
