Ultrasound assisted extraction (UAE) is widely used in recent times for its benefits, but it is difficult to find literature that comprehensively addresses the effect of UAE-specific parameters such as temperature, frequency, power, solvent type, and solvent to material ratio on extracted compounds and their functionality. There is no review done so far on the effects of all UAE parameters on polyphenol extracts to guide the design of extraction protocols. This review therefore focuses on the effects of UAE parameters on the yield and composition, as well as the effects of the UAE on the antioxidant, anticancer, and antimicrobial properties of phenolic extracts. Higher extraction temperatures above 50 °C are degradative to polyphenols in extracts; lower frequencies within the power ultrasound range below 40 kHz are most effective; polyphenol yield generally increases with increasing power, but with a threshold, beyond which no significant increase is observed; and higher ultrasound power produces free hydroxyl radicals which degrade polyphenols, especially in the presence of high water content. A comparative assessment of literature showed that, UAE does not only contribute to increased extraction yield of polyphenols, but also better preserves and increases the biological activity of polyphenol extracts compared to traditional maceration and Soxhlet extraction. A full picture of UAE is given to serve as a reference material on the control of UAE parameters for desired results and efficiency.

超声辅助萃取（UAE）由于其优点而在最近被广泛使用，但是很难找到能全面解决诸如温度，频率，功率，溶剂类型和溶剂与物料比之类的UAE特定参数的影响的文献。提取的化合物及其功能。到目前为止，还没有对所有阿拉伯联合酋长国参数对多酚提取物的影响进行指导，以指导提取方案的设计。因此，本综述着重于阿联酋参数对产量和组成的影响，以及阿联酋对酚类提取物的抗氧化，抗癌和抗菌特性的影响。高于50°C的较高提取温度会降解提取物中的多酚。低于40 kHz的功率超声范围内的较低频率最为有效；多酚的收率通常随功率的增加而增加，但有一个阈值，超过该阈值则没有发现明显的增加；更高的超声功率会产生自由羟基，这些自由基会降解多酚，尤其是在高含水量的情况下。文献的比较评估表明，与传统的浸软法和索氏提取法相比，阿联酋不仅有助于提高多酚的提取率，而且可以更好地保存和提高多酚提取物的生物活性。给出了阿联酋的全貌，以作为控制阿联酋参数以获得所需结果和效率的参考资料。更高的超声功率会产生自由羟基，这些自由基会降解多酚，尤其是在高含水量的情况下。文献的比较评估表明，与传统的浸软法和索氏提取法相比，阿联酋不仅有助于提高多酚的提取率，而且可以更好地保存和提高多酚提取物的生物活性。给出了阿联酋的全貌，以作为控制阿联酋参数以获得所需结果和效率的参考资料。更高的超声功率会产生自由羟基，这些自由基会降解多酚，尤其是在高含水量的情况下。文献的比较评估表明，与传统的浸软法和索氏提取法相比，阿联酋不仅有助于提高多酚的提取率，而且可以更好地保存和提高多酚提取物的生物活性。给出了阿联酋的全貌，以作为控制阿联酋参数以获得所需结果和效率的参考资料。与传统浸软法和索氏提取法相比，它还能更好地保存和提高多酚提取物的生物活性。给出了阿联酋的全貌，以作为控制阿联酋参数以获得所需结果和效率的参考资料。与传统浸软法和索氏提取法相比，它还能更好地保存和提高多酚提取物的生物活性。给出了阿联酋的全貌，以作为控制阿联酋参数以获得所需结果和效率的参考资料。
