摘要

本研究采用水、pH为9.5的氨溶液和己烷对冻干的卡姆（Myrciaria dubia）果实进行超声辅助提取。采用23因子实验设计对每种溶剂进行评估，以评估振幅、溶剂固比和温度对提取物得率和抗氧化潜力的影响。结果与常规动态浸渍法（DM）的结果进行了比较。水和氨溶液pH为9.5时，UAE时间为20 min，己烷为30 min。结果在固料比为22 mL g−1，水处理温度为35℃，水处理振幅为90%时，收率最高，为47.78%。平均而言，阿联酋的提取量比DM多出约26%，只需要十分之一的提取时间，从而显著降低了能耗。所有提取物均表现出抗氧化活性，其中水提液的抗氧化活性最高（3056 μmol TE·g−1）。此外，它还显示出比抗坏血酸更强的抗菌活性。在水提取物中也检测到高浓度的抗坏血酸和酚类化合物。结论以水为溶剂，可比较不同极性和pH值，效果最佳。从经济和环境的角度来看，这一结果是有利的。此外，提取物所表现出的特性表明，它可以用作营养保健品，甚至可以用于食品工业，从而使这种原料的提取物具有附加值。©2025化学工业学会（SCI）。

Ultrasound-assisted extraction with water of lyophilized camu-camu (Myrciaria dubia) resulted in high antioxidant and antimicrobial inhibition

BACKGROUND

In this study, lyophilized camu-camu (Myrciaria dubia) fruits were subjected to ultrasound-assisted extraction (UAE) using water, ammonia solution pH 9.5, and hexane. Each solvent was evaluated following a 2³ factorial experimental design to assess the effects of amplitude, solvent-to-solid ratio, and temperature on extract yield and antioxidant potential. The results were compared to those obtained by the conventional method of dynamic maceration (DM). The UAE times were 20 min for water and ammonia solution pH 9.5, and 30 min for hexane.

RESULTS

The highest yield (47.78%) was reached with an amplitude of 90% for water, a solid-to-sample ratio of 22 mL g⁻¹, and a temperature of 35 °C for water. On average, UAE yielded approximately 26% more extract than DM, requiring only one-tenth of the extraction time, resulting in significantly lower energy consumption. Although all extracts exhibited antioxidant activity, the aqueous extract showed the highest value (3056 μmol TE·g⁻¹). Furthermore, it demonstrated stronger antimicrobial activity than ascorbic acid. High concentrations of ascorbic acid and phenolic compounds were also detected in the aqueous extract.

CONCLUSION

When using water as a solvent, the best results were achieved enabling the comparison among different polarities and pH values. This result is advantageous from an economic and environmental point of view. In addition, the characteristics that the extract expressed showed that it can be used as a nutraceutical or even in the food industry, enabling an added value to the extract from this raw material. © 2025 Society of Chemical Industry (SCI).
