| Abstract: | In this paper,the extraction technology of flavonoids from Cinnamomum camphor leaves was studied by ultrasonic. The total flavonoid was determined via the spectrophotometry method at 510nm with rutin as the standard. The influences of the ethanol concentration,the ratio of solid and liquid,the ultrasonic time,the ultrasonic power and the ultrasonic temperature on the extraction efficiency were investigated. The L9 (34)orthogonal experiment showed that the optimum extraction condition was:extraction time 40 min,ethanol concentration 60%,the ratio of solid and liquid 1:20,ultrasonic power 400 W. The best extraction content of flavonoid was 10.437 mg/g. |
