 Bioactive and nutritional enrich Prunus arminica oil was extracted first time with ultrasonic assisted procedure. Process was optimized by central composite model based on independent variables :solvent seed ratio, sonic power and three levels. Time, temperature and particle size were the dependent variables. Actual and predicted yields differences <1, multiple regression 0.941 showed the adequacy of the model. The sonic power 300W and 10/1mL g-1 solvent seed ratio were found significant variables according to P value. The results of the yield 54.0%, dominancy of oleic acid, scanning microscopic images of seeds, IC50 value 25.1µg µL-1 and the inhibition against gram positive and negative microorganisms revealed the ultrasonic extraction technique more  efficient compared to Soxhlet extraction with 51.73% yield and 27.4µg µL-1 IC50.  10mL g-1 solvent, 300W sonication, 50oC and 30min makes the extraction  cost effective and environment friendly and can step ahead to replace conventional methods for edible oils commercial production.
