Abstract

Abstract: This study optimized the headspace solid phase microextraction (HS-SPME) conditions for the analysis of the volatile constituents of flaxseed oil from Xinjiang by gas chromatography-mass spectrometry (GC-MS). The optimum HS-SPME conditions established were as follows: 40 min extraction using a DVB/CAR/PDMS fiber at 50 ℃ with magnetic stirring followed by 4 min desorption. Under these conditions, a total of 46 volatile compounds were identified consisting mainly of aldehydes, ketones, alcohols, acids, esters, alkanes and heterocyclics and other miscellaneous compounds with aldehydes, heterocyclics and alcohols being predominant among these, accounting for 30.14%, 12.73% and 9.25% of the total identified components, respectively. A good chromatographic separation was achieved in this study.

Key words: headspace solid phase microextraction coupled to gas chromatography-mass spectrometry (HS-SPME-GC-MS), flaxseeds oil, volatile constituents, analysis
