Sažetak
Strawberry tree (Arbutus unedo L.) honey is a rare monfloral bitter honey that originates from the Mediterranean area (Corsica, Croatia, Portugal, Sardinia, and Spain) and possesses many beneficial health effects due to its strong antioxidant activity and high phenolic content. The aim of this study was to determine the polyphenolic profile (“fingerprint”), the total phenolic content and radical scavenging capacity of strawberry tree honey from the Pelješac peninsula, Croatia. Polyphenolic profiling was performed by ultra-high performance liquid chromatograph (UHPLC) coupled to hybrid mass spectrometer (LTQ Orbitrap MS). Fifty-five polyphenolics (phenolic acids and flavonoids) were identified according to their characteristic mass spectra and fragmentation pattern. Strawberry tree honey showed higher phenolic content (1038 mg gallic acid equivalents per kg of honey) and stronger DPPH (2, 2′-diphenyl-1-picrylhydrazyl) scavenging activity (3.32 mmol Trolox equivalents per kg of honey) compared to the monofloral honeys of other botanical origins. Our results indicate that strawberry tree honey has great potential as a health promoting food due to the presence of large quantities of polyphenolic compounds.
