Polyphenol Contents and Antioxidant Activity of Lyophilized Aqueous Extract of Propolis from Erzurum, Turkey
Food and Chemical Toxicology, Article in Press
Propolis, an extremely complex resinous material, exhibits valuable pharmacological and biological properties attributed to the presence of polyphenols.
In this study, we determined the antioxidant properties of lyophilized aqueous extract of propolis (LAEP) from Erzurum province of Turkey and correlated the values with total levels of polyphenolic compounds…
Quantitative amounts of caffeic acid, ferulic acid, syringic acid, ellagic acid, quercetin, α-tocopherol, pyrogallol, p-hydroxybenzoic acid, vanillin, p-coumaric acid, gallic acid and ascorbic acid were detected by high performance liquid chromatography and tandem mass spectrometry (LC-MS/MS).
This study will bring an innovation for further studies with regard to the antioxidant properties of LAEP.
