Sequential extraction (SE) using supercritical CO plus ethanol was applied to separate resin from bacuri fruit shell, where process parameters such as particle size, pressure and cosolvent use were studied. The extracts obtained were also analyzed for phenolic compounds and antioxidant capacity. The extraction results showed that SE was able to separate the resin, which is the first report described in the literature, resulting in a patent. Furthermore, the smaller particle size (0.25 mm) showed the higher extraction rates, providing good yields of lipid extracts (up to 10.09 wt%) and ethanolic extracts (up to 13.78 wt%). The extracts presented good levels of phenolic compounds, which was associated with its high antioxidant capacity. Thus, the application of SE added value to bacuri fruit shell, enabling new strands for potential applications in the food, pharmaceutical and cosmetic industries, placing this by-product in the Amazon bioeconomy scenario.

顺序萃取是从 bacuri 果壳中分离树脂的开创性方法


采用超临界 CO2 加乙醇的顺序萃取 (SE) 方法从 Bacuri 果壳中分离树脂，并研究了颗粒尺寸、压力和助溶剂使用等工艺参数。还分析了获得的提取物的酚类化合物和抗氧化能力。提取结果表明SE能够分离树脂，这是文献中描述的第一个报告，并获得了专利。此外，较小的粒径（0.25 mm）显示出较高的提取率，提供了脂质提取物（高达 10.09 wt%）和乙醇提取物（高达 13.78 wt%）的良好产率。这些提取物呈现出良好水平的酚类化合物，这与其高抗氧化能力有关。因此，SE 的应用为 bacuri 果壳增加了价值，为食品、制药和化妆品行业的潜在应用提供了新的线索，从而将该副产品置于亚马逊生物经济场景中。
