Flame atomic-absorption spectrometry was applied for determination of some macroelements (Ca, Fe, K, Mg, Mn, Zn) in dried aerial parts of the wild and cultivated Teucrium species (Lamiaceae) growing 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 procedure proposed here involves microwave-assisted sample digestion using a mixture of HNO3/H2O2. Wild specimens generally contained higher contents of Ca, K and Mn than the cultivated ones; the opposite was true of Fe, Mg and Zn.
