Abstract

Headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography (GC-FID) was explored to determine the fingerprinting characteristic of Zingiber zerumbet L. volatiles to differentiate between different ginger species. The effect of different fibers [polydimethylsiloxane (PDMS, 7lm), polyacrylate (PA, 85lm)], different temperature and time on the HS-SPME-GC was investigated by using response surface methodology coupled with full factorial experimental design. The area percentage of the major sesquiterpenes (Zerumbone and a-humulene) were 56.3±4.7% and 47.5±27.2% with PA fiber, respectively at optimum condition of 70�C and 30min. ValidationofthedevelopedHS-SPME-GCmethodwithlimitsofdetection and quantification for zerumbone was 0.09 and 0.28lg/g, respectively, demonstrating the suitable sensitivity of HS-SPME-GC methodforthequantificationofsesquiterpenes.Therefore,thesimplicity of HS-SPME-GC makes it a convenient tool for qualitative and quantitative comparison of different ginger species targeting at the markersesquiterpenemolecule,zerumbone.
