Abstract

Abstract

Aromatic compounds in Wanxiang longans were extracted by using three different solid phase microextraction(SPME)fibers,i.e.,50/30μm DVB/CAR/PDMS,75μm CAR/PDMS,and 65μm PDMS/DVB,on GC-MS analysis for comparison.A total of 55 aromatics were detected.The main volatile components were alkenes and esters,including 1,3,6-Octatriene,3,7-dimethyl-,(Z),ethyl acetate,and diethyl phthalate.The 50/30μm DVB/CAR/PDMS fiber showed a high sensitivity and the best extraction effect on alkenes and esters among three,while 75μm CAR/PDMS had a wide absorption selectivity and the highest amounts of the aromatic compounds.The 65μm PDMS/DVB fiber had the lowest absorption capacity,as well as the least amounts of the target substances for detection.It was concluded that either CAR/PDMS or DVB/CAR/PDMS could be adequately applied for the determination.
