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/Et 2 O 1 : 2 ( v / v ) and B: CH 2 Cl 2 ) 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.
