Abstract

Abstract: Cucurbiturils (CB) were investigated as a new coating materials for solid phase microextraction (SPME) and were used for the extraction of the volatile components in round cardamon seed followed by gas chromatography. The preparation method for CB[6] SPME is simple, rapid and provides thermally stable layer with good repeatability for multiple extraction. To evaluate the extraction capability of CB[6] SPME, steam distillation and commercial SPME fibers of PDMS/ CAR and PDMS/DVB were also used for comparison. The results show that CB[6] SPME can extract similar components to SD and the commercial fibers, but achieve higher relative peak area percent for the late-eluted components, which is probably originates from the specific molecular structure and interactions of cucurbiturils with analytes of interest. The present work demonstrates the great potential of cucurbiturils as a new type of SPME coating materials.

Key words: Cucurbituril, Solid phase microextraction(SPME), Gas chromatography, Round cardamon seed
