This study investigated the potential use of microwave energy as an effective technique for the extraction of essential oil (EO) from some plant species belonging to Lamiaceae family growing in Egypt, involving Origanum majorana L., Mentha pipereta L., Mentha longifolia L., Origanum syriacum L., Lavandula angustifolia L., Rosmarinus officinalis L., and Thymus vulgaris L., in comparison with conventional extraction using hydrodistillation (HD) approach, in terms of extraction time, oil yields, and chemical composition. The results showed that the use of microwave in a relevant technique, namely microwave‐assisted hydrodistillation (MAHD) required an extraction of 60 minutes, while HD required 180 minutes. In general, EO yield being extracted by MAHD was higher than those extracted by HD. Gas chromatography in combination with mass spectrometry (GC/MS) analysis indicated noticeable quantitative changes in EOs composition extracted by MAHD and HD extraction methods. Except for O majorana L., GC/MS analysis of extracted oils using MAHD showed higher amounts of oxygenated constituents compared to HD extraction. The results of this study introduced MAHD as rapid, economical and environmental friendly extraction method. A comparative analysis was stated here between the EOs of all plant species under study on chemometric tools such as principal components analysis (PCA) and agglomerative hierarchical clustering (AHC). In general, the PCA results showed that there is significant variation between species in the quality and quantity of EO composition. However, no significant difference is observed based on the extraction method used (HD and MAHD).

通过化学计量学工具，对使用常规和微波辅助加氢蒸馏提取方法提取的某些亚麻科物种的精油化学成分进行分析

这项研究调查的潜在用途微波炉能源作为一种有效的技术为挥发油属于唇形科一些植物物种在埃及成长的提取（EO），涉及墨角兰属，薄荷pipereta L.，欧薄荷L.，牛至，薰衣草，迷迭香和百里香与使用加氢蒸馏（HD）方法进行常规萃取相比，在萃取时间，产油量和化学组成方面都具有优势。结果表明，在相关技术中使用微波，即微波辅助水蒸馏（MAHD）需要提取60分钟，而HD需要180分钟。通常，MAHD提取的EO产量高于HD提取的EO。气相色谱与质谱分析（GC / MS）相结合表明，通过MAHD和HD提取方法提取的EOs组成有明显的定量变化。除了Ø马约拉纳L. ，与HD提取相比，使用MAHD提取的油进行GC / MS分析表明，含氧成分的含量更高。这项研究的结果介绍了MAHD作为一种快速，经济和环保的提取方法。在这里，对正在使用化学计量工具（例如主成分分析（PCA）和聚集层次聚类（AHC））进行研究的所有植物物种的EO之间进行了比较分析。通常，PCA结果表明，EO组成的质量和数量在物种之间存在显着差异。但是，根据所使用的提取方法（HD和MAHD），没有观察到明显差异。
