For this purpose four different honey bee race (Apis mellifera caucasica, A. m. carnica, A. m. syriaca and A. m. anatoliaca) naturally have been in Turkey were placed in the same isolated apiary; and Propolis was harvested from these races. chemical contents of alcoholic extractions of the harvested propolis were were analyzed by liquid chromatography-tandem mass spectrometry (LCMS / MS). In addition that, the pollen content of the same propolis samples were determined with a microscope. According to the LCMS / MS results the propolis samples collected by different honey bee race differed significantly in terms of quercetin and ferulic acid. Data obtained from polen analyses revealed that Fabaceae and Apiaceae (PD <45%) families were mostly detected in propolis samples obtained from different races. Although the polen from the Campanulaceae family was dedected only in the propolis samples from A. m. anatoliaca race, thr polen from Caryophyllaceae family was found in other propolis samples collected by A. m caucasica races. The results of this study showed that different honey bee races tend to different plant sources and the content of propolis may differ according to the bee races. © 2021, Centenary University.
