In this study, an ultrasound assisted ethanolic extraction technique was used for the first time with success to extract oil from Pistacia vera L.The influence of extraction temperature (25, 37.5, 50°C), extraction time (10, 20, 30 min), and solvent to solid ratio (2:1, 4:1, 6:1) on oil efficiency was studied. Ultrasound-assisted extraction is a sustainable extraction technology that uses non-toxic organic solvents like ethanol instead of traditional solvents. According to numerical optimization, the ideal extraction parameters were 32.74°C extraction temperature, 29.47 min extraction time, and 5.94:1 extraction solvent to solid ratio. At these ideal conditions, oil yield is predicted to be 23.54% and experimentally obtained to be 22.04%. The study discovered that linear and quadratic levels of extraction time, as well as interaction levels of extraction time and solvent to solid ratio, had a significant effect on oil yield. It can be stated that the ultrasound-assisted ethanolic method is effective in providing high oil yields compared to traditional methods, reducing extraction time and temperature, and allowing the use of alternative green solvents.
