Abstract

This article stands to introduce microwave assisted extraction (MAE) as a more effective method for extraction of Anastatica hierochuntica (L) essential oils (EOs) compared to traditional hydrodistillation (HD) and steam distillation (SD) methods. Analysis of EOs by gas chromatography-mass spectrometry (GC/MS) showed significant differences in the constituents and percentages of the obtained oils. Using MAE and HD obtained oxygenated monoterpenes 50.79% whereas SD obtained sesquiterpene hydrocarbons 79.84% as major contents of the extracted oils. This is the first report of EO composition of the aerials parts of A. heirochunatica. It offered several advantages of MAE technique as a green method with shorter extraction time (60 min) and better yield.
