This study aims to determine which solvent is the best for the solubility of the propolis by using
concentrations of total polyphenols and flavonoids, ferric reducing antioxidant power (FRAP) assay, and total antioxidant status (TAS) in extracts of propolis from different provinces of Türkiye
prepared with water, ethanol, dimethyl sulfoxide (DMSO), glycerol and acetone. Propolis samples
were lyophilized in the same solvents except for that glycerol and acetone. Total concentrations of
polyphenols and flavonoids, FRAP, and TAS of both normal and lyophilized extracts were found
be consistent when compared with each other. After extraction of propolis and evaluation of the
total polyphenol and flavonoid content and antioxidant capacity, we concluded that it is mostly
dissolved in DMSO, and after that in ethanol, acetone, glycerol respectively, and the least in water
according to our extraction and analysis methods.
