Abstract

LEAL, Alexandre Soares et al. Determination of metals in medicinal plants highly consumed in Brazil. Braz. J. Pharm. Sci. [online]. 2013, vol.49, n.3, pp.599-607. ISSN 2175-9790.  https://doi.org/10.1590/S1984-82502013000300022.

In this work, samples of the medicinal plants: Boldo (Peumus boldus), Castanha da Índia (Aesculus hippocastanum), Chá Verde (Camelia sinensis), Erva Cidreira (Melissa officinalis), Espinheira Santa (Maytenus ilicifolia), Guaraná (Paullinia cupana), Maracujá (Passiflora sp.), Mulungu (Erythrina velutina), Sene (Cassia angustifolia) and Valeriana (Valeriana officinalis) were evaluated BY using the Neutron Activation Analysis technique (NAA- k0) in order to determine the levels of metals and other chemical contaminants. The results showed the presence of non essential elements to the human body. The diversity of chemical impurities found even at low concentration levels, considering the potential for chronic toxicity of these elements, reinforces the need to improve the implementation of good practices by growers and traders, and the hypothesis of lack of quality control in plant products.

Keywords : Neutron activation analysis; Medicinal plants; Metals [determination in medicinal plants]; Chemical contaminants; Plant products [quality control].
