Özet

Many analytical methods for detecting metals in plant materials require decomposition of the sample. Hence, the mineralization procedure is of great importance to obtain correct results. The aim of this study was to assess the performance of selected digestion methods for the determination of some metals in the aerial parts of Scutellaria species, such as Scutellaria orientalis ssp. pectinata "SOSpc" and Scutellaria orientalis ssp. pinnatifida "SOSpn", and ripe berries of Juniperus species, such as Juniperus oxycedrus ssp. oxycedrus "JO" and Juniperus nana "JN", and then find the levels of Ca, Cd, Co, Cu, Fe, K, Li, Mg, Mn, Na, Ni, Pb and Zn. Three digestion methods were used to homogenise and analyse samples for the above-mentioned elements. Microwave-assisted and wet ashing procedures were applied to digest the samples. After digestion, elements determinations were done by using flame atomic spectrometry, apart from Ca, K, Li and Na, analysed by atomic emission spectroscopy.
