Sažetak
Phacelia tanacetifolia Benth. honey (14 samples) collected in Poland was characterized by melissopalynological analysis, color determination (CIE L"a*b*C-ab*h(ab)degrees coordinates) and volatiles (VOCs) composition. VOCs were isolated by headspace solid-phase microextraction (HS-SPME, two fibers) and ultrasound-assisted solvent extraction (USE, two solvents) and analyzed by GC MS. Principal component analysis (PCA) and hierarchical-tree clustering (HTC) were applied to show trends and form groups and to indicate the most representative unifloral samples. Six samples were pointed out with average pollen 74.9% and color parameters (L = 85.1 ; a* = -0.8 ; b* = 27.9 ; C-ab* = 27.9 ; h(ab)* = 91.9) that were significantly correlated. High abundance of trans-linalool oxide (27.3-45.9%) that was significantly correlated with the pollen percentages, hexan-1-ol (4.4-5.7%) and lavender lactone (0.8%- 1.5%) were characteristic for their headspace. Cis- norisoprenoids, mainly (E)-/(Z)-3-oxo-rewo-aionol (4.7-5.4% ; 6.9-9.4%) and vomifoliol (9.0-13.0%) dominated in their USE extracts.
