Abstract
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.
Highlights
The consumption of medicinal plants for therapeutic purposes is recognized as one of the earliest forms of medical practice of mankind
The RDC no 10/2010 provides the registration of herbal medicines and sets out a list of plant species - selected according to its traditional use - having been standardized, for each species, the therapeutic indications, methods of use, quantities to be eaten and care and restrictions to be observed
The excessive accumulation of metals is toxic to most plants (Memon et al, 2001). Considering this issue, the aim of this was to investigate the presence of metals and other elements in plant samples in different forms, such as dry extracts, powders and vegetable drugs, by using neutron activation analysis (NAA)
Summary
The consumption of medicinal plants for therapeutic purposes is recognized as one of the earliest forms of medical practice of mankind.
