Polyphenols are the main group of phytochemicals with several biological activities. Due to the adverse effects of conventional solvent extraction methods, innovative extraction techniques have been used as alternatives to overcome these problems. High voltage electric discharge (HVED) is an eco-friendly innovative extraction technique based on the phenomenon of electrical breakdown in water. This technique induces physical and chemical processes, leading to product fragmentation, cellular damage, and liberation of bioactive compounds. HVED treatment can extract polyphenols at lower temperatures and shorter times than the conventional solvent extraction methods. This review summarizes the effect of HVED processing parameters on the recovery and stability of polyphenols from plant sources. Hydroethanolic solutions improve the HVED-assisted extraction of polyphenols compared to water. Moreover, acidic solvents are suitable for the high recovery and protection of polyphenols during electric discharges. This study revealed the efficacy of the HVED technique in extracting polyphenols for their utilization in the food and pharmaceutical industries.
多酚是具有多种生物活性的主要植物化学物质类别。由于传统溶剂萃取方法存在不利影响，创新的萃取技术已被用作替代方法来克服这些问题。高压放电（HVED）是一种基于水中电击穿现象的环保创新萃取技术。该技术引发物理和化学过程，导致产物破碎、细胞损伤以及生物活性化合物的释放。与传统溶剂萃取方法相比，HVED处理能够在更低温度和更短时间内萃取出多酚。本综述总结了HVED加工参数对从植物来源中回收多酚及其稳定性的影响。与水相比，乙醇水溶液可提高HVED辅助萃取多酚的效果。此外，酸性溶剂适合在放电过程中高效回收和保护多酚。本研究揭示了HVED技术在萃取多酚以用于食品和制药行业方面的有效性。
