In this work, we investigated the effects of the nominal ultrasonic power (160-640 W) and process time (0.5-5.0 min) on the phenolic compounds recovery and antioxidant activity from araticum peel. The individual and synergistic effects of the process variables on the phenolic recovery were estimated using a full factorial experimental design. Operating at high nominal ultrasonic powers was possible to obtain high phenolic yields and antioxidant activities at short process times (≤ 5 min). The HPLC-ESI-QTOF-MS/MS analysis revealed that the araticum peel sample possessed 142 phytochemicals, 123 of which had not been reported in literature for this raw material yet. The most abundant phenolic compounds recovered were epicatechin, rutin, chlorogenic acid, catechin and ferulic acid. Thus, high-intensity ultrasound technology proved to be a simple, efficient, fast and low environmental impact method for obtaining phenolic compounds from araticum peel. In addition, araticum peel showed to be a promising source bioactive natural phenolics for further applications in the food, nutraceutical, cosmetic and pharmaceutical industries.

在这项工作中，我们研究了标称超声波功率（160-640 W）和处理时间（0.5-5.0分钟）对从花生皮中回收酚类化合物和抗氧化活性的影响。使用全因子实验设计估算了工艺变量对酚类回收的个体和协同作用。在短时间内（≤5分钟）以高标称超声功率运行可能获得较高的酚类收率和抗氧化活性。HPLC-ESI-QTOF-MS / MS分析显示，花生皮样品中含有142种植物化学物质，其中123种尚未在文献中报道过。回收的最丰富的酚类化合物是表儿茶素，芦丁，绿原酸，儿茶素和阿魏酸。因此，高强度超声技术被证明是一种简单的方法，于从花生皮中获得酚类化合物的高效，快速和低环境影响的方法。另外，花生果皮被证明是有前途的生物活性天然酚类物质，可进一步用于食品，营养保健品，化妆品和制药行业。
