Abstract In the present work, ultrasound was combined with three-phase partitioning (UA-TPP) for the extraction of curcuminoids from Curcuma longa. The effect of various process parameters viz. solvents, irradiation time, ammonium sulphate concentration, ratio of turmeric aqueous slurry to t-butanol, turmeric powder to aqueous ratio, and ultrasonic power along with duty cycle on UA-TPP was examined. The yield of 67.15 mg/g was achieved using UA-TPP in 20 min irradiation time at room temperature (30 ± 2 °C) using 30% (w/v) ammonium sulphate saturation, 1:1 (v/v) turmeric aqueous slurry to t-butanol ratio, 1:30 (w/v) turmeric powder to solvent ratio with 22 kHz frequency, 60 W power and 60% (6 sec ON and 4 sec OFF) duty cycle. The comparison study was done based on extraction yields, time, energy requirement and process cost required by UA-TPP, conventional TPP and Soxhlet. UA-TPP found useful not only to enhance the process but also to improve the antioxidant capacity and anti-inflammatory activity of the extract in comparison with TPP.

超声与三相分离法提取姜黄中姜黄素的协同作用及其生物活性特征

摘要 在目前的工作中，超声结合三相分配（UA-TPP）从姜黄中提取姜黄素。各种工艺参数的影响，即。检查了溶剂、辐照时间、硫酸铵浓度、姜黄水浆与叔丁醇的比例、姜黄粉与水的比例、超声波功率以及 UA-TPP 的占空比。在室温 (30 ± 2 °C) 下，使用 30% (w/v) 硫酸铵饱和度、1:1 (v/v) 姜黄水溶液，在 20 分钟辐照时间内使用 UA-TPP 达到 67.15 mg/g浆液与叔丁醇的比例，姜黄粉与溶剂的比例为 1:30 (w/v)，频率为 22 kHz，功率为 60 W，占空比为 60%（开启 6 秒，关闭 4 秒）。比较研究是基于 UA-TPP 所需的提取率、时间、能源需求和工艺成本进行的，传统的 TPP 和索氏。与 TPP 相比，UA-TPP 不仅可以增强该过程，还可以提高提取物的抗氧化能力和抗炎活性。
