Optimization of Ultrasonic Extraction of Flavonoids from Castanea mollissima Blume Shell
Abstract:
Flavonoids extracted from Castanea mollissima Blume shell using response surface methodology by ultrasonic-assisted. The effects of liquid/ materials ratio, ethanol concentration, ultrasonic temperature, and ultrasonic time on the flavonoids extraction rate were investigated by Box-Benhnken center composite design. The results showed that the optimum conditions were as follows: liquid/ materials ratio 8:1 (mL/g), ethanol concentration 40 %, ultrasonic temperature 60 °C, and ultrasonic time 25 min, the highest absorbance was obtained under the optimum conditions, and the extract absorbance can be reached 0.702.
