Characterization of Amino Acids, Polyphenols and Flavonoids of Some Bee Products Collected in the Banat Region

Bee products have a well-known tradition in human apitherapy, due to their numerous healing properties. The aim of this study was to evaluate the chemical characterization of the amino acid, polyphenol and flavonoid content of some bee products, such as apilarnil, royal jelly and propolis. The samples were collected from the apiary located in Caransebeș municipality, Banat region, Romania, in 2022, as well as from the market. Apilarnil and royal jelly were analyzed in pure and lyophilized form, and propolis in pure form and tincture. Our results show that there is great variability in the chemical composition of the three beekeeping products studied, depending on the form of presentation and the source of origin. In the case of amino acids, the highest values ​​were obtained in royal jelly from the own apiary 39.93 mg/g, and for polyphenols and flavonoids, the best results were obtained in the case of pure propolis samples 40.82 mg GAE/g, respectively 268.11 mg QE/g.
