In this study, quality parameters of some commercially sold in Turkey propolis extracts were compared with freshly prepared ethanolic propolis extract (70%). The pH, total phenolic substance, total flavonoid and total antioxidant capacity values of 11 different commercial samples, including aqueous, ethanolic, water‐based and vegetable oil, were compared. As a result, it was determined that ethanolic samples had the highest activity and the activity of propolis with olive oil was very low. It was found that products with high total polyphenol content (TP) had high total antioxidant  values. It was also determined that a standard method was not used for the preparation of commercial propolis samples and that the TP values differ greatly.
