In order to obtain the optimal extraction process of amygdalus pedunculata seed oil, the ultrasonic assisted organic solvent extraction method was used to study the effect of signal factor, such as extraction times,liquid-solid ratio, ultrasonic temperature and ultrasonic time on oil extract yield. Based on the single factor analysis, the orthogonal experiment was designed in order to obtain the optimal extraction process of amygdalus pedunculata seed oil. The results showed that the optimum extraction conditions were as follows： extraction times 3, liquid-solid ratio 8, ultrasonic temperature 45 ℃, ultrasonic time 20 min. The optimized ultrasonic technology can effectively extract amygdalus pedunculata seed oil, and it can have a good application prospect.
