Fennel (seeds of Foeniculum vulgare Mill.) is the widely used aromatic and medicinal plant throughout the world. In this research, supercritical carbon dioxide (SC‐CO₂) extraction was carried out to extract the aromatic extract from F vulgare seeds under various operating conditions, and aromatic extract samples were characterized for properties such as yield and trans‐anethole content. A three‐level Box‐Behnken design from response surface method was applied to optimize the extraction parameters such as pressure, temperature, and extraction time with an aim to obtain high yield and rich trans‐anethole content. The optimum extraction conditions were found to be 177 bar, 40°C and 68 min where the predicted oil yield and trans‐anethole contents were found to be 3.798% and 95 mg/g, respectively. Under the optimum conditions, the experimental oil yield was 3.85%, and the content of trans‐anethole was 94 mg/g. The results were very close to the values predicted by the model. At the same time, the chemical compositions of the oils from two different extraction methods, hydrodistillation and SC‐CO₂, were compared. The chemical constituents of oils from two different extraction methods found to be the same, and they showed slight difference in terms of the quantity of the main chemicals. Antibacterial and antioxidant effects of the oils obtained by the two extraction methods were compared, and they showed similar effects.

茴香粗粉超临界二氧化碳萃取工艺优化。使用Box-Behnken设计在种子产量和反渗透孔含量方面对芳香提取物进行播种

茴香（Foeniculum vulgare Mill的种子）是全世界广泛使用的芳香和药用植物。在这项研究中，进行了超临界二氧化碳（SC-CO ₂）萃取，以在各种操作条件下从低俗种子中提取芳香提取物，并对芳香提取物样品的特性进行了表征，例如收率和反茴香含量。应用响应面法的三级Box-Behnken设计来优化萃取参数，例如压力，温度和萃取时间，目的是获得高收率和丰富的反式茴香脑内容。最佳提取条件为177 bar，40°C和68分钟，预测的油产率和反式茴香脑的含量分别为3.798％和95 mg / g。在最佳条件下，实验产油率为3.85％，反式茴香脑的含量为94 mg / g。结果非常接近模型预测的值。同时，通过两种不同的萃取方法（加氢蒸馏和SC-CO _2）得到的油的化学成分，进行了比较。发现来自两种不同提取方法的油的化学成分是相同的，并且它们在主要化学成分的数量上显示出细微的差异。比较了两种提取方法获得的油的抗菌和抗氧化作用，并显示了相似的作用。
