Sažetak
Thistle (Galactites tomentosa Moench.) honey organic extracts were obtained by headspace solid-phase microextraction (HS-SPME) and ultrasonic solvent extraction (USE) and analyzed by gas chromatography (GC-FID and GC- MS) for the fi rst time. Most abundant headspace compounds were terpenes, particularly linalool derivatives (hotrienol was predominant with a range of 38.6 – 57.5%). 3-Phenyllactic acid dominated in the solvent extracts (77.4 – 86.4%) followed by minor percentages of other shikimate pathway derivatives. After determination of an adequate enantioseparation protocol on Chirallica PST-4 column, the honey solvent extracts were analyzed by high- performance liquid chromatography (HPLC). The chiral analysis revealed high enantiomeric excess (> 95%) of (–)-3-phenyllactic acid in all samples. Therefore, previous fi ndings of chemical markers of thistle honey were extended, providing new potential for advanced chemical fingerprinting (optical pure chemical marker).
