Dymerski, Tomasz published the artcileBotanical and geographical origin characterization of polish honeys by headspace SPME-GC×GC-TOFMS, Quality Control of 21834-92-4, the main research area is VOC geog origin honey microextraction chromatog mass spectrometry Poland.
Volatile organic compounds (VOCs) composition of Polish honeys obtained from various geog. regions was studied. Headspace solid phase microextraction (HS-SPME) using Divinylbenzene/Carboxen/Polydimethylsiloxane-coated fibers was used in combination with comprehensive two-dimensional gas chromatog.-time-of-flight mass spectrometry (GC×GC-TOFMS) because of the complexity of the samples. Acacia, linden, rapeseed, buckwheat and honeydew honeys were studied in this project. A total of 329 compounds were identified during the investigations. Pos. identification of 82 compounds was achieved using anal. standards, while tentative identification of 247 compounds was based on comparison of deconvoluted mass spectra and linear temperature programmed retention indexes (LTPRI) with NIST 2005 library and literature values, resp. Many VOCs identified in Polish honey samples were commonly present in honeys from other geog. regions of Europe (e.g. Italy, Corsica). They included certain acyclic and cyclic alkanes, acyclic and cyclic alkenes, aromatic hydrocarbons, oxygenated aromatic compounds, alcs., aldehydes, ketones, esters, ethers, nitriles, organic sulfides, phenolic compounds and terpenes. GC×GC-TOFMS profiles for the same types of honey samples were remarkably similar. Eight botanic discriminants were selected among all compounds Their identity was confirmed by comparison with authentic standards Furthermore, possible geog. discriminants for Polish honeys were identified, including 19 for acacia, 3 for linden, 3 for rapeseed and buckwheat and 6 for honeydew honeys.
Current Organic Chemistry published new progress about Acacia. 21834-92-4 belongs to class isoquinoline, name is 5-Methyl-2-phenylhex-2-enal, and the molecular formula is C13H16O, Quality Control of 21834-92-4.
