The development of simple, rapid and solvent‐free methods for the analysis of essential oils is highly desirable. Microwave‐assisted headspace solid‐phase microextraction (MA‐HS‐SPME) is a new sampling and concentration technique for the extraction of volatile components in medicinal plants. The main advantages of this method are the reduction of extraction time and of organic solvent. Objective A highly porous Santa Barbara amorphous (SBA‐15)/polyaniline material was prepared in order to produce a SPME fibre. The proposed fibre was evaluated for the extraction of the volatile component of Teucrium polium L. Methodology A homemade MA‐HS‐SPME apparatus was used for the extraction of volatile components. Highly porous SBA‐15/polyaniline materials were prepared for SPME. The prepared nanomaterial was immobilized onto a stainless steel wire for fabrication of the SPME fibre. Results The SBA‐15/polyaniline nanonporous fibre could adsorb volatile components of T. polium efficiently. In comparison with a HD method, the proposed technique could equally monitor almost all the components of the sample, but in an easier way that was rapid and required a much lower amount of sample. Conclusion The experimental results showed that the nanoporous fibre was suitable for the semi‐quantitative study of the composition of essential oils in plant materials and monitoring the variations in the volatile components of the plants.
