Investigation the Different Extraction Temperature Effect of Artvin Savsat Region Propolis PBS Extracts on Antioxidant Properties and Eryhrocyte Hemolysis Inhibition

Propolis, which has been used in traditional medicine for hundreds of years all over the world, is a resinous natural product with a complex content obtained by honey bees by mixing the buds of plants and pollen grains with enzymes they secrete. Propolis may have different contents due to the gathering region, plant source, bee variety and climate of the place where it is collected. Although there are many studies related to different regions, so far the propolis of the Savsat region in Artvin have not been studied yet. The aim of this study is to determine the antioxidant properties (determination of iron reducing power, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, total phenolic and total flavonoid content) of propolis extracts of Artvin Savsat region prepared with phosphate buffer salt solution (PBS) prepared at different temperatures (45 and 60 degrees C) and to determine the erythrocyte hemolysis inhibition properties of the extracts. Total phenolic (11.91 +/- 0.5-24.14 +/- 1.38 mg gallic acid equivalent to g propolis) and total flavonoid (1.79 +/- 0.03-2.13 +/- 0.07 mg quercetin equivalent to g propolis) content of PBS extracts, iron power determination (12.80 +/- 0.36-27.15 +/- 0.12 mg ascorbic acid equivalent to g propolis), 2,2-diphenyl-1-picrilhydrazyl (DPPH) radical scavenging activity (%22.86 +/- 0.5-31.24 +/- 1.33) and erythrocyte hemolysis inhibition (%55.58 +/- 0.57-96.37 +/- 0.02) were determined using spectrophotometric methods. As a result of the experiments, it was determined that the extract with PBS obtained at a temperature of 60 degrees C was higher than the extract obtained at 45 degrees C, in terms of antioxidant properties and erythrocyte hemolysis inhibition ratio. Further studies are required to identify molecules that inhibit erythrocyte hemolysis in extracts and have antioxidant properties.
