Today, one of the problems of the food industry is the use of synthetic compounds as preservatives, the potential dangers of each of these compounds for human health have been proven. Currently synthetic antioxidants such as butyl hydroxyl anisole and butyl hydroxyl toluene are used in the oil industry. The purpose of this research is to investigate the effect of ultrasound pretreatment on the extraction of phenolic compounds from the herb flower on oxidative stability of the oil containing the resulting extract. In this research, from the extract of Artemisia annua flower with the help of ultrasound pretreatment with a fixed intensity of 24KHz and a fixed temperature of the laboratory and the application times of ultrasound waves is 10, 20 and 30 minutes and methanol solvent extraction by maceration method with a fixed time of 48 hours and it was used a stabilize soybean oil at a constant temperature in the laboratory (control). With the help of the response level method, the most appropriate ultrasonic pretreatment for 30 minutes. Then, different concentrations of 0,50, 100, 250, 500 and 1000 ppm were prepared after ultrasonic pretreatment for 30 minutes. The results showed that the pretreatment with a concentration 0f 1000 ppm with the highest amount of phenolic compound extaction (28/15) mg/g and DPPH free radical inhibitory power (53/30)% was the most suitable sample that was added to the oil and The tests related to the stability of soybean oil including: peroxide index, acid index and thiobarbituric acid index were performed, which according to the results of the tests had an upward trend and the most stabilizing effect was at a concentration of 1000 ppm.
