The present study deals with intensified extraction of curcumin from Curcuma aromatica by employing ultrasound-assisted extraction (UAE) approach also elucidating comparison with the conventional batch extraction to highlight the intensification benefits based on the usage of ultrasound. Understanding into the effect of operational parameters like type of solvent, extraction temperature, solid to solvent ratio and raw material size distribution as well as the equipment operating conditions as frequency and power on the extraction yield has been developed. Based on the results for extraction yield, the optimum conditions for UAE approach were 40 °C as temperature, 1:30 as solid to solvent ratio, 0.09 mm as the mean particle size, 240 W as ultrasonic power, 22 kHz as ultrasonic frequency and ethanol as the most suitable solvent. Under these optimum conditions, the highest extraction yield of 73.18% was achieved in 2 h whereas batch extraction for 14 h resulted in 52.31% yield clearly demonstrating the intensification due to ultrasound. Peleg's model was applied to explain the extraction kinetics of curcumin and the proposed model satisfactorily predicted the rates of extraction of curcumin. Overall, UAE proved to be a better technique in terms of lesser time, lesser heating requirement and additional extraction yield.

与选自C姜黄素加剧提取本研究涉及urcuma郁金通过采用超声辅助提取 (UAE) 方法，还阐明了与传统批量提取的比较，以突出基于超声使用的强化优势。已经深入了解了操作参数（如溶剂类型、提取温度、固溶剂比和原料粒度分布）以及设备操作条件（如频率和功率）对提取率的影响。根据提取率结果，UAE法的最佳条件为温度40°C，固溶剂比1:30，平均粒径0.09 mm，超声功率240 W，超声频率22 kHz，乙醇为最合适的溶剂。在这些最佳条件下，最高提取率为 73。在 2 小时内达到了 18%，而 14 小时的分批提取产生了 52.31% 的产率，这清楚地表明了超声波的强化。Peleg 模型用于解释姜黄素的提取动力学，所提出的模型令人满意地预测了姜黄素的提取率。总的来说，UAE 被证明是一种在更短的时间、更少的加热需求和额外的提取率方面更好的技术。
