Expanding the Knowledge Related to Flavors and Fragrances by Means of Three-Dimensional Preparative Gas Chromatography and Molecular Spectroscopy

As universally known, gas chromatography (GC) coupled with mass spectrometry (MS) allows us to acquire spectra that can be searched in specific databases attain qualitative information on a peak of interest. When not present databases, structure elucidation is required before including new component library: from moment, scientists all around the world will able identify molecule analytical confidence after GC-MS analysis. Conversely, if data are shared commercial even studied and elucidated, it appears unknown or only identifiable basis third-party taken literature, which serious limitation. The paper deals case confirms this assumption. A Myrtus communis L. volatile fraction was tentatively identified based literature data. Despite this, reliable identification could achieved due lack corresponding spectrum MS databases. Afterwards, target isolated reasonable quantity high degree purity for downstream characterization by spectroscopic techniques. For purpose, preparative (prep) GC may appear insufficient isolation components highly complex samples. In study, prep-MDGC system implemented compound interest myrtle oil, consisting three wide-bore columns different selectivity means Deans switch transfer devices. Based NMR GC-FTIR acquired, as 2,2,5,5,7,7-hexamethyl-3,7-dihydro-1-benzofuran-4,6(2H,5H)-dione. Noticeably, known molecule, yet its had never been registered into thus available scientific community. Finally, included first time library, namely FFNSC 5.0 database. aim study highlight opportunity make quickly way registering them searchable improve researchers over world.
