Essential oils extraction from Bunium Persicum (Boiss) was performed using instant controlled pressure drop (in French: Détente Instantanée Contrôlée or DIC) thechnology and optimum extraction conditions were obtained. Response surface methodology (RSM) was used to determine the optimal conditions and the results were 20 s heating time, 3.5 bar pressure, 0.44 mm particle diameter and 9 cycles. Essential oils extraction was also compared with Hydrodistillation (HD), ultrasound-assisted extraction (UAE) and Soxhlet (SOX) extraction. Results show higher efficiency of the DIC than other methods and more oxygenated components were observed. Impact of DIC, HD, UAE and SOX on the morphological structure of the plant was studied by SEM. Antioxidant activity and total phenolic content (TPC) of the extract were determined and comapred by HD. Results show that DIC facilitates achieving to higher TPC and more antioxidant activity.

使用即时控制的压降从Bunium Persicum（Boiss）中提取香精油（法语：DétenteInstantanéeContrôlée或DIC）技术和最佳提取条件。使用响应表面方法（RSM）确定最佳条件，结果为20 s加热时间，3.5 bar压力，0.44 mm粒径和9个循环。还将精油提取与加氢蒸馏（HD），超声辅助提取（UAE）和索氏提取（SOX）提取进行了比较。结果表明，DIC的效率高于其他方法，并且观察到了更多的含氧化合物。通过SEM研究了DIC，HD，UAE和SOX对植物形态结构的影响。测定提取物的抗氧化活性和总酚含量（TPC），并通过HD进行映射。结果表明，DIC有助于达到更高的TPC和更多的抗氧化活性。
