Nanobubbles (NBs) generated-nanojets membrane poration have gained enormous attention. In this study, NBs were fabricated as a novel green approach to assist ionic liquid (IL) [C₄C₁im][BF₄] extraction of polyphenols from Carya cathayensis Sarg. husk. NBs were successfully generated with mean size of 85.47 ± 5 nm, zeta potential of +39 ± 2.24 mV, and concentration of 21.15 ± 0.75 × 10⁸ particles/mL (stable for over 48 h in IL solution). Compared to common solutions extract, IL-NBs extract showed significantly higher (p < 0.05) antioxidant activity and polyphenols yields with a total polyphenol, total flavonoid, and total tannins contents of 85.67 ± 2.05 mg GAE/g DW, 42.44 ± 1.17 mg CE/g DW, and 8.2 ± 0.05 mg TAE/g DW, respectively. The SEM results confirmed that NBs’ nanojets caused morphological destruction of the husk powder. Overall, IL-NBs solution showed better extraction efficiency of polyphenols than other solutions, giving insight into a new “green” nanotechnology-based extraction method.

Nanobubbles (NBs) 产生的纳米喷射膜穿孔获得了极大的关注。在这项研究中，NBs 被制造为一种新的绿色方法，以辅助离子液体 (IL) [C ₄ C ₁ im] [BF ₄ ] 从山核桃中提取多酚。外壳。NBs 成功生成，平均大小为 85.47 ± 5 nm，zeta 电位为 +39 ± 2.24 mV，浓度为 21.15 ± 0.75 × 10 ⁸颗粒/mL（在 IL 溶液中稳定超过 48 小时）。与普通溶液提取物相比，IL-NBs 提取物显示出显着更高的 ( p < 0.05) 抗氧化活性和多酚产量，总多酚、总黄酮和总单宁含量分别为 85.67 ± 2.05 mg GAE/g DW、42.44 ± 1.17 mg CE/g DW 和 8.2 ± 0.05 mg TAE/g DW . SEM 结果证实 NBs 的纳米射流造成了壳粉的形态破坏。总体而言，IL-NBs 解决方案显示出比其他解决方案更好的多酚提取效率，从而深入了解一种基于“绿色”纳米技术的新提取方法。
