Consumers has become more conscious about their food and ingredients and they began to prefer foods that have health benefits. Hence, examination of bioactive compounds of food products has become important. Propolis, which is a bee product known to have many health benefits due to the bioactive substances it contains, has become a very popular food supplement. However, in our country, propolis produced with different solvent extractions without the use of alcohol within the scope of Halal food, as well as the presence of propolis produced with alcohol extraction cause the bioactive feature of propolis sold in the markets to vary. This situation also prevents standardization. In this study; it is aimed to determine the bioactive components of commercial propolis samples and show the results comparatively. A total of 14 different commercial propolis products were obtained from domestic and foreign brands. They contained different solvents (such as alcohol, water, propylene glycol) and were packaged in dropper bottles and disposable sachets. Total phenolic content, total flavonoid content and phenolic profile analysis were performed for each sample. Total phenolic content was determined by spectrophotometric method, phenolic profile and total amount of flavonoid substance were determined by chromatographic method at LC-MS-MS. A total of 43 different phenolic substance were analysed. Since the propolis content of the products declared on the labels were different, the total phenolic content and the total flavonoid content were calculated based on the fact that they contained 50% propolis. It was found that, the water based propolis product in the disposable sachet had the highest amount of the total phenolic and total flavonoid content. At the same time, 42 of the 43 phenolic components analyzed, were detected at this product hence it was ranked at the top in terms of the variety of phenolic components. On the other hand, any flavonoid component could be detected in the other two water based propolis products. These differences could be related to the extraction solvent and method and/or the quality of the raw material. For this reason, consumers need to know the propolis content and the solvent type in the product as well as the amount of bioactive components. At this point, it becomes important for the consumers to be able to access the information about the amount of the bioactive components of product they will buy.
