An excellent high-efficiency natural deep eutectic solvent (NADES, ChCl-MA) was screened out and integrated with pulse-ultrasonication technique for extracting phenolic compounds from Carya cathayensis Sarg. peels (CCSPs). Single factor experiment combined with response surface methodology (RSM) using Box-Behnken design (BBD) were employed to investigate significant factors and optimize their influence on extraction of phenolic compounds. Significant synergistic effect triggered by ChCl-MA based pulse-ultrasonication over other methods used alone were proved by comparative study concerning a variety of bioactive components and antioxidant activities. The second-order kinetic model was developed and validated (R > 0.99) to describe the extraction process and its mechanism; and second-order kinetic extraction rate constant (k), saturation concentration (C), and initial extraction rate (h) were calculated. FT-IR, DSC and SEM results further demonstrated synergistic effect and influence during extraction. Overall, this study provided a green and high-efficiency alternative for the recovery of various phenolics compounds from plant source by-products.
一种高效的天然深共晶溶剂（NADES，ChCl-MA）被筛选出来，并与脉冲超声技术结合，从山核桃外果皮（CCSPs）中提取酚类化合物。采用单因素实验结合响应面法（RSM）中的 Box-Behnken 设计（BBD），研究了显著因素及其对酚类化合物提取的影响。通过对各种生物活性成分和抗氧化活性的比较研究，证明了基于 ChCl-MA 的脉冲超声协同作用优于单独使用的其他方法。建立并验证了（R>0.99）二阶动力学模型来描述提取过程及其机制，并计算了二阶动力学提取速率常数（k）、饱和浓度（C）和初始提取速率（h）。FT-IR、DSC 和 SEM 结果进一步证明了提取过程中的协同作用和影响。总的来说，这项研究为从植物副产物中回收各种酚类化合物提供了一种绿色高效的替代方法。
