Copper, cobalt and nickel concentrations were determined by the Zeeman graphite furnace atomic absorption spectrometry (ZGFAAS) in dried aerial parts of the wild and cultivated Teucrium species (Lamiaceae) wide-spread in Croatia: T. arduini L., T. chamaedrys L., T. flavum L., T. montanum L., T. polium L. and T. scordium L. subsp. scordioides Schreb. The investigated species contained Cu 9.30-51.20 mg kg-1, Co 0.02-4.31 mg kg-1 and Ni 0.61-9.65 mg kg-1 of the dry drug. The higher concentrations were found in cultivated plants, with the exception of the representatives of wild T. montanum with the far highest quantities of all metal ions examined.
