Karabagias, Ioannis K. published the artcileA targeted chemometric evaluation of the volatile compounds of Quercus ilex honey in relation to its provenance, Formula: C10H20O2, the main research area is Quercus ilex honey volatile compound chemometric evaluation.
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.
