Weighing paper-assisted magnetic ionic liquid headspace single-drop microextraction using microwave distillation followed by gas chromatography-mass spectrometry was successfully developed to determine the essential oil components in lavender. The magnetic ionic liquid 1-octyl-3-methylimidazolium tetrachloroferrate was successfully synthesized and used as the optimal extraction solvent. An aliquot of 9 μL of magnetic ionic liquid could be stably suspended on the weighing paper for long time extraction. The increase of the extractant volume resulted in a significantly enhanced in extracting efficiency of the weighing paper-assisted magnetic ionic liquid headspace single-drop microextraction than traditional headspace single-drop microextraction method. In this experiment, the optimal conditions were 1-octyl-3-methylimidazolium tetrachloroferrate as the extraction solvent, extraction time of 12 min, microwave power of 600 W, cyclohexane as back-extractant and sample amount of 30 mg. The developed method was successfully applied to analyze 16 lavender samples from three different harvest years. A total of 39 compounds in lavender were identified and the principal component analysis provided a clear separation between those lavender samples harvested in different years. The results indicated that the proposed weighing paper-assisted magnetic ionic liquid headspace single-drop microextraction is a novel, fast, simple and sensitive microextration technique for the determination of the essential oil components in lavender.
