This study reports the oil extraction from cumaru seeds by compressed propane (CPE). Extractions were performed varying temperature (20, 40, 60 °C), pressure (2, 6, 10 MPa), and average particle size (2, 1.7, 1.0, 0.5 mm). The results were compared respect to coumarin content, total phenolic content, antimicrobial and antioxidant activities. It was obtained that 98 % of the total oil present in the seeds can be recovered at 60 °C, 10 MPa, and 0.5 mm. The fatty acid profile indicated that the oil obtained with CPE is richer in unsaturated fatty acids than samples obtained in Soxhlet extraction with n-hexane. Antimicrobial activity was found against Klebsiella pneumoniae, Staphylococcus aureus, and Escherichia coli. Antioxidant activity increased with the coumarin content and both activities were influenced by the coumarin presence (0.11−0.50 wt%). The results showed that CPE is selective for cumaru oil extraction with low contents of coumarin within the constant extraction rate period.

这项研究报告了通过压缩丙烷（CPE）从cumaru种子中提取油。在不同温度（20、40、60°C），压力（2、6、10 MPa）和平均粒径（2、1.7、1.0、0.5 mm）下进行萃取。比较了香豆素含量，总酚含量，抗菌和抗氧化活性的结果。获得的种子中存在的总油的98％可以在60°C，10 MPa和0.5 mm的条件下回收。脂肪酸谱表明，与CPE获得的油是不饱和脂肪酸比索氏提取与获得的样品更丰富Ñ正己烷。发现对肺炎克雷伯菌，金黄色葡萄球菌和大肠杆菌具有抗菌活性。抗氧化剂的活性随香豆素含量的增加而增加，两种活性都受到香豆素含量（0.11-0.50 wt％）的影响。结果表明，在恒定的萃取速率期内，CPE对香豆素含量低的香豆油具有选择性。
