Cnidoscolus quercifolius seeds were subjected to oil extraction with supercritical CO₂ at 40, 50, and 60 °C and 20, 25, and 30 MPa for 120 min at 5 g min⁻¹. The oils obtained were evaluated from the viewpoint of their yield, composition, and antioxidant activity; they were compared with the oil obtained using the conventional Soxhlet extraction method with n-hexane. Sovovás’ mathematical model was used to adjust the kinetic curves. The highest oil yield (41.0 wt%) was obtained at 60 °C and 30 MPa and corresponded to ∼87% of the Soxhlet yield. In this condition, the highest yields of tocopherols and β-sitosterol were obtained, i.e., 8.87 and 51.6 mg 100 g_seed⁻¹, respectively. The oils extracted by both the methods showed a similar fatty acid composition with a predominance of linoleic acid (∼60%). The highest antioxidant activity was equivalent to 6.82 mmol of trolox per kg of oil.

在40、50和60℃以及20、25和30 MPa下，在5 g min ^-1下用超临界CO ₂提取油酸猕猴桃种子，历时120分钟。从其收率，组成和抗氧化活性的角度评估所得油；他们使用与以往的索氏抽提法得到的油进行比较Ñ正己烷。索沃瓦斯的数学模型用于调整动力学曲线。在60°C和30 MPa下获得最高的油产率（41.0 wt％），相当于索氏提取率的〜87％。在这种条件下，生育酚和β-谷甾醇的产量最高，即8.87和51.6 mg 100 g_种子^-1， 分别。两种方法提取的油均显示出相似的脂肪酸组成，其中主要是亚油酸（约60％）。最高的抗氧化活性相当于每公斤油中6.82 mmol的trolox。
