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.eninfo:eu-repo/semantics/closedAccessChemical-compositionConstituentsProductsAcidPropolisPhenolFlavonoidAntioxidantMarmara regionScience & technologyLife sciences & biomedicineEntomologyArticle00090784490000154254863310.1080/00218839.2022.2157582
