“…The aforementioned aldehydes have been reported previously to enhance the volatile fraction of Spanish [2,5,6,10], and Hellenic thyme honey [2], or even in Turkish pine honey [16] The lower content of octanal, nonanal and decanal in fir honeys (dark colored honeys) as compared to flower or thyme honeys, is in agreement with the results reported by Petretto et al [17] for Moroccan dark colored honeys. It should also be mentioned that, undecanal and dodecanal were detected only in flower honeys from Samos Island.…”

“…However, formic acid ethyl ester, ethoxymethylene-propanedioic acid diethyl ester and benzene acetic acid ethyl ester (ethyl phenyl acetate) were detected only in thyme honeys from Kos Island. These ethyl ester derivatives have not been reported previously, to enhance the volatile pattern of Spanish thyme honeys [5,6].…”

The philosophy of the present work was to investigate the volatile profile, pigment content, and in vitro radical scavenging activity of Hellenic honeys, using aqueous honey solutions. Twenty-one honey samples representing flower, thyme and fir honeys were donated from professional beekeepers during two consecutive harvesting years, from three different regions in Hellas.Volatile profile was estimated using headspace solid phase micro extraction coupled to gas chromatography/mass spectrometry (HSPME-GC/MS). For semi-quantification purposes the internal standard method was used. Pigment content along with the in vitro radical scavenging activity was determined using spectrophotometric methods.Results showed that the twenty-one honeys analyzed exhibited variations in volatile profile, pigment content and antioxidant activity depending on the floral source (p<0.05). Honey aroma was found to be the outcome of the combination of different class compounds, namely: carboxylic acids, alcohols, aldehydes, ketones, benzene derivatives, etc. The most pronounced aromas were recorded for flower honey, whereas fir honey possessed the highest pigment content and radical scavenging activity (p<0.05). In addition, specific volatiles (2-hydroxy-benzoic acid methyl ester, alpha-pinene, para-cymene, and delta-3-carene) were perfectly correlated (Pearson's correlation coefficient r = 1) with radical scavenging activity (p<0.01).The present results enhance the quality control and authenticity of Hellenic honey and may be of great interest to a wider audience including: consumers, honey industry, and honey researchers, at an international level.

Salix spp. nectar honey volatiles of Croatian origin were analyzed by headspace solid-phase microextraction (HS-SPME) and ultrasonic solvent extraction (USE), followed by gas chromatography and mass spectrometry (GC, GC/MS). Isolated volatiles were found in the honey headspace and extracts with almost exclusive distribution of several abundant compounds (e.g., phenylacetic acid, pinocembrin, 8-hydroxy-4,7-dimethylcoumarin, and 3-hydroxy-trans-β-damascone in the extracts, or safranal and lilac alcohols in the headspace). Comparison with Croatian Salix spp. honeydew honey revealed similarities regarding distribution of important shikimate pathway derivatives (e.g., high percentage of phenylacetic acid) and several norisoprenoids (α-isophorone and 4-oxoisophorone). On the other hand, distinct features of this honey were occurrence of compounds such as pinocembrin, 8-hydroxy-4,7-dimethylcoumarin, phenylacetonitrile, norisoprenoids (major ones: 3-hydroxy-trans-β-damascenone and trans-β-damascone), more pronounced variability of linalool-derived compounds, as well as the abundance of 3-methylpropanoic acid, 3-methylbutanoic acid, 2-methylpentanoic acid, and 3-methylpentan-1-ol.

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.
