Abstract:"Chemical analysis of Asphodelus microcarpus Salzm. et Viv. honey is of great importance, since melissopalynology does not allow the unambiguous determination of its botanical origin. Therefore, the volatile compounds of eight unifloral asphodel honeys have been investigated for the first time. The honey extracts were obtained by headspace solid-phase microextraction (HS-SPME) and ultrasonicsolvent extraction (USE) and analyzed by GC and GC/MS. In the honey headspace, 31 volatile compounds were identified with high percentages of 2-phenylacetaldehyde (2; 14.8-34.7%), followed by somewhat lower percentages of methyl syringate (1; 10.5-11.5%). Compound 2 is not a specific marker of the botanical origin of the honey, but its high percentage can be emphasized as headspace characteristic of asphodel honey. The extraction solvent for all the samples was selected after extracting a representative sample with pentane, Et(2)O, pentane/Et(2)O 1:2 (v/v), and CH(2)Cl(2) . Compound 1 was the major constituent of all the USE extracts (46.8-87.0%). According to these preliminary results, all the honey samples were extracted by USE with the solvent pentane/Et(2)O 1:2. A total of 60 volatile compounds were identified with 1 as predominant compound (69.4-87.0%), pointing out 1 as Asphodelus honey volatile marker"
