Abstract: Objective:To study extraction technology of flavonoids from hawthorn fruits.Methods:The ethanol supersonic extraction experiments for flavonoids from hawthorn fruits were concluded on;reducing the blood fat with flavonoids from hawthorn fruits.Results:The conditions for ethanol supersonic extraction are:Solvent:70% ethanol,supersonic wave frequency 40kHz,time of supersonic action 15min and ratio of material to liquid 1:40 times.Conclusion:The ethanol supersonic extraction showed that the method possesses the advantages of simple operation short extraction time high purity good yield and no need of heat.The residue is unharmful to environment and can be used multipurposely.

Key words: flavonoid of hawthorn, ultrasonic, reduce the blood fat, the total cholesterols
