Abstract:		"The compounds responsible for highly individual aroma profile of Coriandrum sativum L. honey were isolated by headspace solid-phase microextraction (HS-SPME; used fibers: A: polydimethylsiloxane (PDMS)/divinylbenzene (DVB) and B: divinylbenzene/carboxen/polydimethylsiloxane), as well as ultrasonic solvent extraction (USE; used solvents: A: pentane/Et2 O 1 : 2 (v/v) and B: CH2 Cl2 ) and analyzed by gas chromatography (GC) and mass spectrometry (MS). Unusual chromatographic profiles were obtained containing derivatives of linalool/oxygenated methoxybenzene. trans-Linalool oxide (11.1%; 14.6%) dominated in the headspace, followed by other linalool derivatives (such as cis/trans-anhydrolinalool oxide (5.0%; 5.9%), isomers of lilac aldehyde/alcohol (14.9%; 13.8%) or p-menth-1-en-9-al (15.6%; 18.5%)), octanal, and several low-molecular-weight esters. The major compounds in the solvent extracts were oxygenated methoxybenzene derivatives such as 3,4,5-trimethoxybenzyl alcohol (26.3%; 24.7%), methyl syringate (23.8%; 11.7%), and 3,4-dimethoxybenzyl alcohol (5.6%; 13.9%). Another group of abundant compounds in the extracts were derivatives of linalool (e.g., (E)/(Z)-2,6-dimethylocta-2,7-diene-1,6-diol (17.8%; 16.1%)). Among the compounds identified, cis/trans-anhydrolinalool oxides and 3,4,5-trimethoxybenzyl alcohol can be useful as chemical markers of coriander honey"
