“…Since the physical state of the sample to be analyzed should generally be liquid, a digestion procedure is necessary prior to AAS determination of metals in plant and food samples (Ezoddin et al 2010;Rihawy et al 2010;Chalapathi et al 2010;Fang et al 2010;Bagdatlioglu et al 2010;Kolachi et al 2010a, b;Carneiro et al 2011;Mol 2011). Wet digestion by using acidic solutions is important methodology for the digestion of trace heavy metals in solid samples before AAS determination.…”

The trace element contents of seven kinds of herbal plants and spice samples retailed in local markets in Kayseri-Turkey were determined by flame atomic absorption spectrometry after digestion with HNO(3)/H(2)O(2) mixture. The concentration ranges for the studied elements were found as 6.0-15.2, 0-32.2, 80.0-324.8, 8.1-386.3, and 13.1-36.2 μg/g for copper, nickel, iron, manganese, and zinc, respectively. The levels of cobalt, lead, and chromium ions in all the investigated samples were found to be below the detection limit of flame atomic absorption spectrometry. The results found in the present work were compared with values in the literature.

A humanidade faz uso de plantas medicinais para prevenção e o tratamento de diversas doenças desde a antiguidade até os tempos atuais, aproximadamente, 80% da população ainda utiliza esse recurso medicinal como um dos primeiros tipos de tratamento não convencional para cuidar da saúde. A população da Amazônia tem como hábito a utilização de várias plantas medicinais, por isso, este estudo teve como objetivo determinar a concentração de Ca, Fe, Mg, Mn e Zn em cinco plantas medicinais e em seus chás, comercializadas no Mercado do Ver-o-Peso, localizado na cidade de Belém-PA. As plantas estudadas foram: carqueja (Baccharis trimera), chapéu de couro (Echinodorus grandiflorus), confrei (Symphytum officinale L.), erva doce (Pimpinela anisum) e losna (Artemisia absinthium L.). As amostras foram digeridas em forno de micro-ondas com cavidade e, posteriormente, analisadas por espectrometria de absorção atômica com chama (FAAS). Os resultados mostraram que nos chás, as plantas que apresentaram os maiores teores dos elementos foram a losna para o Ca e Zn (3668,40 e 17,03 mg kg-1, respectivamente), o chapéu de couro para o Fe e Mn (282,38 e 156,64 mg kg-1, respectivamente) e a erva doce para o Mg com 2108,50 mg kg-1. A análise elementar em plantas medicinais serve como um dado complementar referente à sua avaliação nutricional, com isso, neste estudo foi possível constatar que as plantas analisadas não apresentam risco de toxicidade quando ingerido os seus chás.

“…Due to the importance of the elements present in medicinal herbs, several studies have been carried out to determine their concentrations by using the following techniques: atomic absorption spectrometry (AAS) ( Malik et al, 2008 ; Kolasani, Xu & Millikan, 2011 ; Ayivor et al, 2012 ; Malik et al, 2013 ), inductively coupled plasma-mass spectrometry (ICP-MS) ( Tokalioğlu, 2012 ; Zhang et al, 2013 ), inductively coupled plasma-atomic emission spectrometry (ICP-AES) ( Leśniewicz, Jaworska & Zyrnicki, 2006 ; Başgel & Erdemoğlu, 2006 ), inductively coupled plasma-optical emission spectrometry (ICP-OES) ( Malik et al, 2008 ; Pytlakowska et al, 2012 ; Malik et al, 2013 ), neutron activation analysis (NAA) ( Ayivor et al, 2012 ; Fatima, Waheed & Zaidi, 2013 ; Waheed & Fatima, 2013 ), particle induced X-ray emission (PIXE) ( Naga Raju et al, 2006 ; Rihawy et al, 2010 ; Venkateswara Rao et al, 2013 ) and X-ray fluorescence (XRF) ( Marguí, Hidalgo & Queralt, 2005 ; Khuder et al, 2009 ; Hondrogiannis et al, 2012 ; De La Calle et al, 2013 ).…”

Some plants popularly employed for the treatment of peptic ulcers have proved to be attractive sources of new drugs. Despite extensive research, the pharmacological and toxicological potentials of these plants are not fully understood. In this context, the aim of this work was to analyze the multielemental composition of the methanolic extracts of three of those plants, Alchornea glandulosa (AG), Davilla elliptica (DE) and Davilla nitida (DN), with the intention of contributing to the understanding of the mechanisms of action of these extracts. For this purpose, we used the analytical technique of total reflection X-ray fluorescence (TXRF) by synchrotron radiation at the Brazilian Synchrotron Light Source (LNLS/CNPEM). It was possible to determine the concentrations of the elements: P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb and Br in all of the samples. Selenium (Se) was detected only in the DN extract. An inverse relationship between the concentrations of elements with proven effectiveness and the gastroprotective activity of extracts considering induction protocols with ethanol and non-steroidal anti-inflammatory drugs (NSAIDs) was obtained. This data suggests that the function of the extract is not only associated with providing the elements for restoring the gastric mucosa but that it also promotes the displacement of these elements from other parts of the mucosa to the damaged area. Correlations between the concentrations of the elements were also obtained. In the DE extract, which is the most effective extract for both induction protocols, the obtained correlations were above 70% among almost all of the elements, and no anticorrelations were found. For the other two extracts, in the less effective extract (AG) anticorrelations above 70% were predominantly found. Meanwhile, in the DN extract, a few high anticorrelations were found, which may explain its intermediate stage of effectiveness.
