Abstract

This study investigated various properties of raw propolis samples from Marmara region of Turkey. Total phenolic content (TPF), total flavonoid (TFC) values, condensed tannin content (CTC) and phenolic profiles of ethanolic extracts (70%) were analyzed. Antioxidant activities were tested using the Ferric (III) reduction/antioxidant capacity (FRAP) and 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging methods. Phenolic profiles of the samples were analyzed using high performance liquid chromatography (RP-HPLC-UV) method. TPC, TFC and CTC values in the samples ranged from 52.9 to 203.5 mg GAE/g, 13.6 to 43.9 mg QUE/g, and 2.0 and 2.9 mg CTE/g, respectively. Caffeic acid phenyl ester (CAPE), chrysin, pinocembrin, rutin, and t-cinnamic acid were detected as the common phenolic components in all samples. In conclusion, Marmara region propolis is a rich source of bioactive compounds, especially flavonoids with antioxidant properties.
