UV-VIS Determination of Polyphenols and Flavonols in Slavonian Propolis

Propolis is one of the most important bee products because of its impact on human health. The chemical composition of propolis is complex and depend on various factors but polyphenols and flavonols, as essential compounds in it, play significant role in the inhibition of certain enzymes, stimulation of hormones, free radical absorbance capacity and helping in disease curing. It is well known that the propolis have many antibacterial, antitumorial, antifungal, antiiflammatory and antiHIV characteristics. It can also be used as local anaesthetic compound. The samples were collected in 2013. UV-VIS determination of polyphenols (with Folin-Ciocalteu reagent) and flavonols (with AlCl3 reagent) in Slavonian propolis showed mutual proportionality and obtained results are comparable with literature. Dry matter content couldn’t be directly related to total concentration of polyphenols and flavonols.
