Abstract

In this study, ionic liquid microwave-assisted hydrodistillation (IL-MAHD) was employed to overcome the challenges of substantial emulsification and low extraction yield which occur in the extraction process of Angelica sinensis essential oil (AEO). Additionally, an online detection system was introduced into the AEO extractor to enable real-time monitoring during the extraction process. Optimal conditions were determined as follows: material-to-liquid of 1:10, ionic liquid concentration of 0.5%, microwave power of 400 W, extraction time of 4 h, condensation temperature of 20 °C, and cooling temperature of 40 °C. Under these optimized conditions, the AEO yield reached 0.7707%, marking a 1.4066-fold increase compared to microwave-assisted hydrodistillation (MAHD) and a 3.7615-fold increase compared to hydrodistillation (HD). Meanwhile, IL-MAHD exhibited the highest relative content of (Z)-ligustilide (73.424%), and the corresponding AEO displayed significant anti-inflammatory and antioxidant effects at concentrations of 7.8125, 15.625, and 31.25 µg/g. The results of extraction kinetics and online monitoring suggested that the IL-MAHD achieved the fastest extraction yield of AEO. This study provides a new perspective on exploring a potential cost-efficient technology for the industrial extraction of essential oils.

离子液体微波辅助水蒸馏萃取当归精油及其抗炎和抗氧化活性

本研究采用离子液体微波辅助水蒸馏法（IL-MAHD）克服了精油（AEO）萃取过程中出现的大量乳化和低萃取率的难题。此外，还在 AEO 萃取器中引入了在线检测系统，以便在萃取过程中进行实时监控。确定的最佳条件如下：材料与液体的比例为 1:10，离子液体浓度为 0.5%，微波功率为 400W，萃取时间为 4 小时，冷凝温度为 20 °C，冷却温度为 40 °C。在这些优化条件下，AEO的收率达到0.7707%，比微波辅助水蒸馏（MAHD）提高了1.4066倍，比水蒸馏（HD）提高了3.7615倍。同时，IL-MAHD的（）-鬼臼内酯相对含量最高（73.424%），相应的AEO在7.8125、15.625和31.25µg/g浓度下显示出显著的抗炎和抗氧化作用。萃取动力学和在线监测结果表明，IL-MAHD的AEO萃取率最快。这项研究为探索一种潜在的具有成本效益的精油工业萃取技术提供了一个新的视角。
