Characterization of summer savory (Satureja hortensis L.) honey by physico-chemical parameters and chromatographic/spectroscopic techniques (GC-FID/MS, HPLC-DAD, UV/VIS and FTIR-ATR

摘要: Satureja hortensis L. unifloral honey was characterized by pollen analysis, electrical conductivity, pH and extensively chromatographic spectroscopic techniques. UV / VIS spectro-scopy measurements revealed total phenol content of 682.1 mg GAE kg Folin-Ciocalteu assay, antiox-idant capacity DPPH assay 1.7 mmol TEAC FRAP 4.3 Fe2+ as well CIE L*a*b*Cab*h°ab chromaticity coordinates. GC-MS after headspace solid-phase microextraction (HS-SPME) hotrienol (22.8 %) along with other linalool derivatives, benzaldehyde (6.1 %), phenylacetaldehyde (4.9 few norisoprenoids (safranal (7.6 the major). Ultrasonic solvent ex-traction (USE) followed allowed identification methyl syringate (54.7 predominant compound benzene derivatives. HPLC-DAD analysis determined tyrosine (382.0 kg−1), phenylalanine (140.4 kg−1) (39.32 kg−1). Methyl can be considered non-specific chemical markers S. honey. FTIR-ATR spectral characteristics in fingerprinting region were not significantly different from types, but integrated intensity smaller than honeys.
