Supercritical fluid (SFE) and pressurized liquid (PLE) extraction were applied to tucumã-do-Amazonas () almonds (TAA). SFE was performed with CO at different pressures and temperatures, and the extracts were characterized for global yield, fatty acid and triacylglycerol profile, carotenoids, tocols concentration and thermal behavior. PLE was applied to the SFE-defatted almond at different temperatures and ethanol:water mixtures. The PLE extracts were characterized for global yield, total phenolics and antioxidant capacity. SFE global yield was 33 g extract/100 g dry TAA at 25 MPa and 40 °C, containing mainly triacylglycerols from lauric and myristic acids. Regarding tocols, SFE at 25 MPa and 50 °C resulted in 58 µg/g extract. PLE from defatted TAA achieved 24 g extract/100 g defatted TAA and the greatest phenolic content and antioxidant capacities with 75% ethanol at 110 °C. Therefore, TAA is a potential source of valuable compounds to be extracted by SFE and/or PLE.

超临界流体和加压液体提取花过的 tucumã-do-Amazonas (Astrocaryum aculeatum) 杏仁

将超临界流体 (SFE) 和加压液体 (PLE) 萃取应用于 tucumã-do-Amazonas () 杏仁 (TAA)。在不同压力和温度下用 CO 进行 SFE，并对提取物的总体产量、脂肪酸和三酰甘油谱、类胡萝卜素、母育酚浓度和热行为进行了表征。 PLE 在不同温度和乙醇：水混合物下应用于 SFE 脱脂杏仁。对 PLE 提取物的总体产量、总酚类物质和抗氧化能力进行了表征。在 25 MPa 和 40 °C 下，SFE 总体产量为 33 g 提取物/100 g 干燥 TAA，主要含有来自月桂酸和肉豆蔻酸的三酰甘油。关于母育酚，25 MPa 和 50 °C 下的 SFE 产生 58 µg/g 提取物。来自脱脂 TAA 的 PLE 可实现 24 g 提取物/100 g 脱脂 TAA，并在 110 °C 下使用 75% 乙醇实现最大的酚含量和抗氧化能力。因此，TAA 是通过 SFE 和/或 PLE 提取的有价值化合物的潜在来源。
