Ultrasound pretreatment (USP) combined with supercritical CO₂ extraction (SCE) was carried out to obtain Iberis amara seed oil (IASO) in the present study. The maximal oil yield (25.28 ± 0.39 %, w/w, dry basis) acquired by SCE from ultrasound-treated seeds with ultrasonic energy density of 1.25 W/mL during 10 min, was 28 % higher than that obtained from the untreated seeds. Furthermore, the obtained oil samples were determined for physicochemical properties, fatty acid profile, contents of various phytocompounds and antioxidant activity. The results showed that USP + SCE resulted in better oil quality, slightly enhanced the selectivity of monounsaturated fatty acids in the obtained oil, as well as improved the contents of phytocompounds and antioxidant activity of IASO samples, when compared with traditional techniques. Our study revealed that ultrasound pretreatment combined with SCE can be considered efficient and environmentally-friendly for plant oil extraction at industrial scale. Furthermore, IASO has high nutritional value. Therefore, Iberis amara seeds can potentially be used as easily available sources of natural plant oil in the pharmaceutical, biodiesel and dietary supplement industries.

进行超声预处理（USP）和超临界CO ₂萃取（SCE ）相结合，得到伊比利斯伊巴拉斯本研究中的种子油（IASO）。通过SCE在10分钟内从超声处理过的种子中获得的最大油产率（25.28±0.39％，w / w，干基），超声能量密度为1.25 W / mL，比未处理种子高28％。此外，测定获得的油样品的理化性质，脂肪酸谱，各种植物化合物的含量和抗氧化活性。结果表明，与传统技术相比，USP + SCE可以提高油质，稍微提高所得油中单不饱和脂肪酸的选择性，并提高IASO样品的植物化合物含量和抗氧化活性。我们的研究表明，超声预处理与SCE结合可以认为在工业规模的植物油提取中既高效又环保。此外，IASO具有很高的营养价值。因此，伊比里斯（Iberis amara）种子有可能在制药，生物柴油和膳食补充剂行业中用作容易获得的天然植物油来源。
