    Determination of mineral and trace elements in some medicinal herbs and their infusions consumed in Turkey
    (Elsevier, 2006) Basgel, S; Erdemoglu, SB
    Fourteen mineral and trace elements (Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Sr and Zn) were determined in the herbs and their infusions consumed for medical purposes in Turkey such as chamomile (Matricaria chammomile L.), fennel (Foeniculum vulgare), linden (Tilia vulgaris), nettle (Urtica dioical), rosehip (Fr.Rosa caninae), sage (Salvia officinalis) and senna tea (Cassia anqustifolia). Microwave digestion procedure was applied under optimized conditions for dissolution of medicinal herbs. Element concentrations in the medicinal herbs and their infusions were determined by FAAS and ICP-AES. The accuracy and precision were verified against a GBW 07605 Poplar leaves and Tea certified reference material. The mineral and trace element content of medicinal herbs and their infusions showed a wide variability. However, distribution of the elements in the infusions is not high and it is nil especially for Cd, Co, Cr and Pb. (C) 2005 Elsevier B.V. All rights reserved.
