Study on Flavonoids from the Peony Leaves by Ultrasonic Extraction
The extraction of flavonoids from peony leaves was studied recently. We carried out a research on the optimum technology of extracting flavonoids by single and orthogonal factor experiment. Finally we found the optimum conditions were: the ultrasonic temperature is 60 degrees, the ultrasonic time is 20min, the ultrasonic power is 600w, solid-liquid ratio is 1:25. Under this condition, the yield of flavonoids was 1.47% and the content was 8.34%.
