Abstract

GORST-ALLMAN, Charles P.  and  NAUDE, Yvette. Fynbos products: what's in the bottle? An investigation of terpenoid constituents in fynbos products by GCxGC-TOFMS and GC-HRT. S.Afr.j.chem. (Online) [online]. 2016, vol.69, pp.213-217. ISSN 1996-840X.  http://dx.doi.org/10.17159/0379-4350/2016/v69a27.

Several off-the-shelf products (personal care, fragrances and oils, food) were analyzed by solid phase micro-extraction gas chromatography-mass spectrometry to determine the most prevalent volatile compounds responsible for the product aroma. Both one-dimensional and two-dimensional gas chromatography were used, and coupled with low and high-resolution, accurate mass time of flight mass spectrometry. The spectrum of components present in the different products was examined to see if a commonality of constituents could be identified which might lead to a typical fynbos aroma profile.

Keywords : Fynbos; aroma compounds; comprehensive gas chromatography; time of flight mass spectrometry; high-resolution accurate mass.
