This study evaluates the reliability of polystyrene/MgAl-layered double hydroxide as a 3D new nanostructure solid phase
microextraction fiber coating for extraction and determination the essential oil of Grammosciadium platycarpum Boiss. &
Hausskn. growing wild in Maragheh region, East Azerbaijan province, Iran. The Headspace solid phase microextraction
coupled with gas chromatography/mass spectrometric method was applied for analyzing of volatile oils. The Headspace
solid phase microextraction parameters including the extraction temperature and time, sample weight, and water amount
were optimized. The method was compared with traditional hydrodistillation. The analysis of the oils resulted in the
identification of 31 compounds. Linalool (57.31 and 61.05%) and α-humulene (5.62 and 4.82%) were found to be the
major components, in hydrodistillation and headspace solid phase microextraction methods, respectively. The novel 3D
nanostructure fiber coating based on MgAl LDH had the advantages of the strong interaction between analyte and sorbent,
simplicity, high thermal stability and more convenient handling than the other traditional SPME fibers. Although to date,
SPME devices have been used mainly in laboratory applications, recent research has been directed towards remote
monitoring, particularly for clinical, field environmental and industrial hygiene applications.
