In this study, an efficient ionic liquid (IL)-based microwave-assisted extraction (IL-MAE) was employed for the extraction of Heneicos-1-ene from coriander foliage. Quantification of Heneicos-1-ene was carried out using high-performance liquid chromatography. Parameters affecting extraction such as material to solvent ratio (1:10, 1:15, and 1:20), types of IL ([CH3(CH2)3]4NF, [BMIM][PF6], [BMIM][BF4], and [C6H5]4P[Br]), concentration of IL (0.1, 0.5, and 1.0 M), microwave power (200, 500, and 800 W), extraction temperature (50, 70, and 90 °C) and extraction time (2, 6, and 10 min) were evaluated. Response surface methodology was applied to determine the optimum levels of these parameters to get maximum yield. The optimal conditions were achieved at 800 W, 90 °C for 2 min at a material to solvent ratio of 1:10 using 0.1 M solution of [BMIM][BF4], to get maximum predicted yield of Heneicos-1-ene (412.8 mg/100 g) as against 408.5 ± 1.14 mg/100 g for experimental value with 0.991 correlation coefficient. IL-MAE resulted in 5.85 times higher yield as compared to the conventional method (69.77 ± 1.8 mg/100 g).

基于离子液体的微波辅助从香菜叶中提取Heneicos-1-ene，并通过响应面法优化产量参数。

在这项研究中，基于高效离子液体（IL）的微波辅助提取（IL-MAE）用于从香菜叶中提取Heneicos-1-ene。使用高效液相色谱法对Heneicos-1-ene进行定量。影响萃取的参数，例如材料与溶剂的比例（1：10、1：15和1:20），IL类型（[CH3（CH2）3] 4NF，[BMIM] [PF6]，[BMIM] [BF4] ，[C6H5] 4P [Br]），IL浓度（0.1、0.5和1.0 M），微波功率（200、500和800 W），萃取温度（50、70和90°C）和萃取评估时间（2、6和10分钟）。应用响应面方法来确定这些参数的最佳水平，以获得最大的产量。使用0.1 M的[BMIM] [BF4]溶液在材料与溶剂的比例为1:10的情况下，在800 W，90°C下2分钟达到最佳条件，获得Heneicos-1-ene（412.8 mg / 100 g）的最大预测产量，而实验值为408.5±1.14 mg / 100 g，相关系数为0.991。与传统方法（69.77±1.8 mg / 100 g）相比，IL-MAE的产量高5.85倍。
