Flaxseeds were taken as raw material and ultrasonic - assisted extraction technology was used to extract the seed oil. On the basis of single - factor experiments, the optimal technological condition of the ultrasonic - assisted ex-traction was studied with the quadratic orthogonal rotation combination design. Results: The influence order of the factors affecting the oil yield are extraction time > liquid - solid ratio > extraction temperature > ultrasonic frequency. The optimal technological parameters of the oil extraction from flaxseeds using petroleum ether as solvent are as follows: liquid - solid ratio 10 mL/g, extraction temperature 60 ℃, extraction time 35 min, and ultrasonic frequency 60 W. Under the condi-tions, the total oil yield after three times' extraction is 45.75 %, and the extraction rate reaches as high as 93.27 %.
