Since the quality and biological value of bees’ products depend on the chemical composition and taking into consideration environmental conditions, the purpose of research is to study the composition of amino acids in leaves of nectar-pollenous plants, pollen, bee bread, honey and bee body all it has theoretical and practical interest. Research of amino acids was performed on amino acid analyzer (AAA-T 339) in the laboratory of Sanopronostic and Sanodiagnostic of the Institute of Physiology and Sanacreatology of Academy of Sciences of Moldova. It was found that leaves of nectar-pollenous plants contained 154 092 mg / g amino acids in pollen - 139 692 mg / g, in honey - 0.851 mg / g, in the body of the bee - 445 785 mg / kg. From the total weight of amino acids in honey the most part has proline - 27.26%, in pollen - glutamine acid - 15.03% and proline - 13.98%, in the leaves of the honey plants - glutamine acid - 17.03% and bee body - 16.72%.
