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.

Propolis is a natural product collected by honeybees from plants especially flowers and buds by mixing with wax and resin and used for many purposes in hive. It is known that propolis has been used in the treatment of various diseases in traditional medicine for many years and has biological activities such as antioxidant, antimicrobial, antiulcer, antitumor, anti-inflammatory. There is increasing interest in alternative approaches to inhibit Helicobacter pylori (H. pylori) and thereby treat many gastric diseases. This study investigated various properties of raw propolis samples from the Marmara region of Turkey. Anti-urease activity was investigated in propolis samples. The anti-urease activity of IC50 values ranged from 1.110 to 5.870 mg/mL. As a result, it can be said that propolis extract is a good inhibitor that can be used in the treatment of H. pylori to improve human health.
