چکیده	Background: In the current study, simultaneous extraction and concentration of the analytes from the headspace on the solid phase microextraction (SPME) fiber were followed by transferring the essential oil components of Salvia hydrangea DC to the headspace with the help of a heating source. Methods: The essential oil components of the plant were extracted and concentrated in a single step. A one-at-the-time optimization procedure was applied to the microextraction conditions by using the nanocomposite fiber of polypyrrole/SBA-15. Results: The results of the essential oil extraction of Salvia hydrangea clearly demonstrated that polypyrrole/SBA-15 fibers were efficient with SPME technique. The acceptable SPME precision in our study was corroborated by the relative standard deviation (RSD) values of less than 15%. Conclusion: In comparison to the hydro-distillation (HD) method, the SPME technique could equally provide monitoring of almost all the constituents of the studied essential oil in an easier way and shorter time with much lower amounts of the plant sample. The results of the essential oil extraction of Salvia hydrangea clearly demonstrated that polypyrrole/SBA-15 fibers were efficient with SPME technique.
