Abstract Introduction Research on the volatile oil composition of Thymus kotschyanus Boiss was conducted by applying mesoporous organosilica based on alkylimidazolium ionic liquid (PMO‐IL) as a fibre coating material via a method referred to as microwave‐assisted headspace solid‐phase microextraction (MA‐HS‐SPME). Methodology This technique entails microwave irradiation of the sample and collection of the volatile sample components. These components are further introduced into a gas chromatography–mass spectrometry (GC–MS) injection port for further analysis. A simplex method was used for the optimisation of three different parameters affecting the efficiency of the extraction. Conclusion The MA‐HS‐SPME method proved to be the most suitable technique in oil determination and extraction from Thymus kotschyanus owing to its advantageous aspects of cost effectiveness, simplicity and solvent independence.
