This study aimed to evaluate the effects of the high-intensity ultrasound (HIUS) on the recovery of phenolic compounds from the leaves, fruit pulp, and seed of Eugenia calycina Cambess. The impact of using different modes of application of the same ultrasound-specific energy (kJ/g) was examined. Ultrasound energy performance was assessed employing two different HIUS treatments for each part plant. The same specific energy levels of 2 and 5 kJ/g were applied, varying nominal power and processing time. The HIUS treatments of low-power and long-time (LPLT) and high-power and short-time (HPST) were performed at 100 W, and 475 W. LPLT treatment was non-thermal processing, while HPST was a thermal treatment. The HPST treatment showed more efficiency in the recovery of the phenolic compounds to specific energies. The leaves were the plant part that exhibited the highest content of phenolic compounds and antioxidant activity. The LC-MS analysis also showed ellagic acid and myricitrin as the main phenolic compounds in all botanical parts evaluated. The SEM showed a physical change in plant structure because of HIUS. However, the FTIR spectra indicated that the chemical functional groups were not affected by the acoustic energy. Despite the HPST treatment increased the medium temperature, the stability of antioxidant compounds was preserved. The interaction of the high nominal power, short processing time, and moderate temperature employed in the HPST extraction procedure positively affected the extraction yield of phenolic compounds from the Eugenia calycina.

本研究的目的是评估在从叶酚类化合物，果肉的回收率高强度超声（HIUS）的影响，和种子的尤金尼亚calycina坎贝斯。研究了使用相同超声比能量（kJ / g）的不同应用方式的影响。对于每个零件工厂，采用两种不同的HIUS处理来评估超声能量性能。施加了2和5 kJ / g的相同比能，改变了标称功率和处理时间。在100 W和475 W下对低功率和长时间（LPLT）以及大功率和短时间（HPST）进行HIUS处理。LPLT处理是非热处理，而HPST是热处理。HPST处理在将酚类化合物回收至特定能量方面显示出更高的效率。叶子是植物部分，具有最高的酚类化合物含量和抗氧化活性。LC-MS分析还显示，鞣花酸和肉豆蔻素是所评估的所有植物部位中的主要酚类化合物。SEM显示由于HIUS，植物结构发生了物理变化。然而，FTIR光谱表明化学官能团不受声能的影响。尽管HPST处理提高了介质温度，但仍保留了抗氧化剂的稳定性。HPST萃取过程中使用的高标称功率，较短的处理时间和适中的温度之间的相互作用对从苯酚中提取酚类化合物的产率产生了积极影响。尽管HPST处理提高了介质温度，但仍保留了抗氧化剂的稳定性。HPST萃取过程中使用的高标称功率，较短的处理时间和适中的温度之间的相互作用对从苯酚中提取酚类化合物的产率产生了积极影响。尽管HPST处理提高了介质温度，但仍保留了抗氧化剂的稳定性。HPST萃取过程中使用的高标称功率，较短的处理时间和适中的温度之间的相互作用对从苯酚中提取酚类化合物的产率产生了积极影响。番木瓜（Eugenia calycina）。
