Analysis of Volatile Components in Absolute Oil of Spartium junceum L. with Comprehensive Two-Dimensional Gas Chromatography/Time-of-Flight Mass Spectrometry
2012
The volatile components in absolute oil of Spartium junceum L.were identified by GC×GC/TOFMS and fingerprint spectrum was established by means of MS library search,retention index comparison,standard and document verification.The results showed that: 1) 150 volatile components were identified,and the major components included methyl linoleate(10.70%),linolenic acid(7.90%),palmitic acid(7.66%),methyl 2-aminobenzoate(5.30%),mushroom alcohol(3.65%),ethyl laurate(3.43%),benzyl benzoate(2.97%),ethyl linoleate(2.97%),ethyl decanoate(2.68%),methyl stearate(2.68%),linalool(2.55%),α-farnesene(2.46%),phenethanol(2.22%),methyl oleate(2.05%),ethyl stearate(2.05%),and methyl linolenate(2.00%).2) The group fractions of n-alkane,cyclical aromatic compounds and noncyclic compounds were well separated on Rxi-5Sil MS×DB-17ht column systems.
