The polyphenol content of propolis has received a lot of attention due to the benign biological properties noted in the chemical composition studies. However, there are very limited studies about other chemical components found in trace amounts in nature which contribute to the therapeutic properties of propolis. The present study, therefore, investigated the amino acid and vitamin composition of propolis. Propolis harvested by 60 colonies of Apis mellifera caucasica belonged to local non-migratory beekeepers. The A. m. caucasica is known for its distinctive propolis collecting capability which native to the secluded Ardahan Province of Turkey. Vitamin (Thiamine, Riboflavin) combinations of propolis were determined using the HPLC (High-Performance Liquid Chromatography) fluorescent detector. An amino acid analysis was also performed with the UFLC (Ultra-Fast Liquid Chromatography) system consisting of binary pump and UV/VIS.
