Abstract
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.
