Extraction and Determination of Total Flavanone of Polygonum Aviculare L by Ultrasonic Wave

Bao Yu-min

Abstract

Objective:The total flavanone were extracted from polygonum aviculare L and contents were checked.Methods:Ethanol was selected as solvent,the total flavanone were extracted from polygonum aviculare L with ultrasonic wave and Using spectrophotome try to extract and check the flavanone of polygonum aviculare L.Results:Measure sample in average content of the total flavonoid is 1.88%,Average recovery rate is 100.95%.Conclusion:Using ultrasonic wave can speed up the velocity of reaction and improve extract efficiency.
