Taking walnut green husk as materials,six factors including ultrasonic power,ethanol concentration,ultrasonic temperature,ultrasonic time,ratio of solid to liquid and standing time were selected,on the basis of single-factor experiments,the Box-Behnken design(BBD) was used to establish a quadric regression equation for predicting the yield of flavonoids.The results showed that the ethanol volume fraction 62%,ultrasonic temperature 51℃,ultrasonic time 31 min,standing time 6.5 min was the… CONTINUE READING
