Analysis of Volatile Constituents from FructusMume by Headspace Solid-phase Micro-extraction Coupled to Gas Chromatography-Mass Spectrometry

Optimal conditions for the extraction of volatile constituents from FructusMume concrete using solid-phase micro-extraction method(SPME) were studied by gas chromatography-mass spectrometry.The effect of different SPME fibers,equilibrium temperature and sampling time on analysis result were investigated by using orthogonal experimental design.Based on the analyse of gas chromatography-mass spectrometry(GC-MS) combining with the principle of the greatest amount of information content,a good extracting efficiency was obtained by polydimethylsiloxane(PDMS) fiber with sampling time of 45 min and equilibrium temperature of 70 ℃.The 38 volatile flavor components of FructusMume were separated and identified,and the main volatile components were furfural(24.88%),3-hydroxy-2-methylbenzaldehyde(13.57%) and 5-methylfurfural(10.16%),respectively.
