The technology of ultrasonic extraction was applied to extract flavonoids from Chongqing grapefruit peel. Ultraviolet spec-trophotometry method was used to determine the content of flavonoids in extracting solution of Chongqing grapefruit peel. The better technical condition is the extraction time was 1 hour,the solid-to-liquid ratio was 1∶20(g·mL-1),the concentration of alcohol was 65%,and the pH value was 7. 0. Under this condition,it can get the 0. 598 extraction percentage of flavonoids.
