Sažetak
Among the compounds identified (ultrasonic solvent extraction followed by GC-MS), markers of the Salix spp. nectar honey botanical origin were phenylacetic acid, benzoic acid, 2- hydroxybenzoic acid, 4-hydroxybenzoic acid, 4- hydroxybenzyl alcohol and other compounds that originated from shikimate biosynthetic pathway, similar as for Salix spp. honeydew honey. All these compounds probably originated from Salix spp., a well known source of salicylic acid and its derivatives. High abundance of 3- methylpropanoic acid, 3-methylbutanoic acid, 2- methylpentanoic acid and 3-methylpentan-1-ol can be noted as specific for the nectar honey and several of them were found with lower percentages in the honeydew honey. The presence of pinocembrin and 8-hydroxy-4, 7- dimethylcoumarin can be emphasized, since they were not identified in the honeydew honey. Phenylacetonitrile was present only in the nectar honey. Another group of abundant compounds were terepens, particularly linalool derived compounds. In comparison with the honeydew honey much more pronounced qualitative and quantitative composition of lilac aldehydes and alcohols were found. Norisoprenoids can be additionally considered as characteristic for the nectar honey, particularly 3-hydroxy-trans- β-damascenone, trans-β-damascone, 4- ketosiophorone, α-isophorone and others.
