This study reports the extraction of oil from organic blackberry (Rubus spp. Xavante cultivar) performed using supercritical CO₂ (scCO₂), compressed propane, n-hexane and petroleum ether. The extractions with compressed propane showed higher extraction yield and extraction rate, when compared to those performed with scCO₂. All the oils obtained represent a rich source of unsaturated fatty acid (around 93%) composed mainly by linoleic acid. Furthermore, the extraction using scCO₂ resulted an oil with high total phenolic compounds (113.49 mg GAE 100 g^-1) and antioxidant activity as given by the ABTS method (2701.74 µmol TE 100 g^-1). On the other hand, compressed propane showed a higher efficiency in extracting β-carotene and the oil obtained with such solvent presented a higher thermal stability (224.70 °C), rather than the oil obtained with scCO₂ (198.83 °C). These results indicate a high potential of this oil for applications in food, pharmaceutical, nutraceutical and cosmetic industries.

这项研究报告的油从有机黑莓提取（悬钩子属物种Xavante栽培品种）利用超临界CO进行₂（SCCO ₂），压缩丙烷，Ñ己烷和石油醚。与用scCO ₂进行的萃取相比，使用压缩丙烷的萃取显示出更高的萃取产率和萃取速率。所有获得的油代表主要由亚油酸组成的丰富的不饱和脂肪酸来源（约93％）。此外，使用scCO ₂萃取得到的油具有较高的总酚类化合物含量（113.49 mg GAE 100 g ^-1），并具有ABTS方法提供的抗氧化活性（2701.74 µmol TE 100 g ^-1））。另一方面，压缩丙烷在提取β-胡萝卜素方面显示出更高的效率，并且用这种溶剂获得的油表现出更高的热稳定性（224.70°C），而不是用scCO ₂（198.83°C）获得的油。这些结果表明该油在食品，制药，营养保健和化妆品工业中的应用潜力很大。
