Proba identyfikacji zwiazkow fenolowych w miodach pszczelich

Metodą HPLC oznaczono zawartość wybranych związków fenolowych w 15 próbkach miodów pszczelich.

The aim of our study was to evaluate and identificate the content of phenolics in 15 samples of honey. The phenolics (absisic acid, ellagic acid, galcic acid) and flavonoids (luteolin, quercetin, kaempferol, apigenin and chrysin) were analyzed by hplc after extraction from honey using procedure reported by lihu yao et al. All of the analyzed honeys contained in different amounts absisic acid, luteolin, quercetin, kaempferol, apigcnin and chrysin. Galcic acid was find in 1 samples and ellagic acid was not find in any samples. The most shares in the total percentage of absorbance in all investigated samples had absisic acid. Rape honey was characterized by the presence of chrysin, heather honey by quercitin and apigenin and accacia honey by luteolin and kaempferol. The obtained results show on differences in phenolic contents of particular monofloral honeys. Further studies will be continued in order to find correlation between botanical origins and phenolic profiles.
