| Abstract: | Total flavonoids was extracted from Raspberry by Ultrasonic Method. The effects of four factors including Ultrason- ic power, ultrasonic time, ethanol concentration, solid - liquid ratio on the yield of total flavonoids were investigated. The optimum technological conditions of total flavonoids extraction were confirmed through single factor test and the orthogonal test. The optimum exaction technology conditions of cloudberry were as follows：Ultrasonic power for high stall, ultrasonic time of 70 min , 60% ethanol concentrationand solid - liquid ratio of 1：25 ;the yield of total flavonoid was 9. 517%. The extraction process was simple, reasonable, and could be used for the determining the content of total flavorioids from the raspberry. |
