The present study aimed at the determination of volatile compounds (VOCs) of Greek Quercus ilex honey, which comprises a rarely studied honeydew honey, from different regions and to characterize its provenance using a targeted chemometric evaluation of the semi-quant. data of VOCs determined with headspace solid phase microextraction coupled to gas chromatog./mass spectrometry (HS-SPME/GC-MS). Principal component anal. (PCA), multivariate anal. of variance (MANOVA) and stepwise linear discriminant anal. (SLDA) showed that provenance affected the volatile composition of Quercus ilex honey. The PCA explained 98.10% of total variance with the factors that maximized the squared cosine to be 10 VOCs: heptane, dimethyl-disulfide, octane, nonane, styrene, alpha-pinene, meta-cymene, DL-limonene, 1-decanol, and tetradecanoic acid Et ester. The SLDA resulted in the formation of linear discriminant functions that provided a classification rate of honey samples according to provenance by ∼80%, based on styrene, eucalyptol, benzeneacetaldehyde, 1-decanol, and tetradecanoic acid Et ester. Considering the complementary results of PLS-VIP (partial least squares anal.-variable importance in projection) eucalyptol, 1-decanol, and tetradecanoic acid Et ester are proposed as volatile indicators of the provenance of Greek Quercus ilex honey. These VOCs were also correlated with the percent of Castanea sativa and Polygonum aviculare pollen grains.Ethyl tetradecanoate (cas: 124-06-1) were involved in the experimental procedure.
Ethyl tetradecanoate(cas: 124-06-1) is a labeled component from essential oil of natural hawthorn perfume. Also frequently used in cosmetics, soaps, and flavorings.Category: esters-buliding-blocksEthyl myristate is a long-chain fatty acid ethyl ester resulting from the formal condensation of the carboxy group of myristic acid with the hydroxy group of ethanol.
