Abstract: Phenolic extracts were isolated from 35 honey and nine beebread samples obtained from different sources in Lithuania by using Amberlite XAD-2 resin. The antioxidant properties of extracts were assessed by the ABTS(.+) radical cation decolourisation and DPPH. radical scavenging activity. It was found that all honey and beebread extracts were able to scavenge free radicals, however their scavenging activity varied in a wide range, on average between 43.0% and 95.7%. The preliminary screening of phenolic compounds in honey samples was performed by high-performance liquid chromatography with UV and mass spectrometer detectors. The results obtained showed that all samples contain p-coumaric acid, kaempferol, chrysin and apigenin. This study demonstrates remarkable variations in antioxidant properties and content of phenolic compounds in honey from different sources; these variations should be considered in using honey as a source of natural dietary antioxidants
