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 the 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，我们研究了名义超声功率（160-640 W）和处理时间（0.5-5.0 分钟）对腰果果皮中酚类化合物回收和抗氧化活性的影响。使用全因子实验设计估计了工艺变量对酚类化合物回收的单独和协同作用。在高名义超声功率下，可以在短的处理时间（≤5 分钟）内获得高的酚类产率和抗氧化活性。HPLC-ESI-QTOF-MS/MS 分析表明，腰果果皮样品中含有 142 种植物化学物质，其中 123 种尚未在该原料的文献中报道过。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从腰果果皮中获得酚类化合物的简单、高效、快速和低环境影响的方法。此外，腰果果皮显示出作为有前途的生物活性天然酚类化合物的来源，可进一步应用于食品、营养保健品、化妆品和制药行业。
