Abstract: Shaddock were taken as materials and ultrasonic-assisted supercritical CO2 extraction method was used to extract naringin from
shaddock. The optimal ultrasonic treatment parameters were investigated using single factor experiment and orthogonal
suggested that the optimized conditions were as follows: ultrasonic power 300W, ultrasonic treatment temperature 60℃ and ratio of sold to
liquid 1:18, ultrasonic treatment time 6 min. Under the optimal conditions, the oil yield reached %
