Artigo IPEN-doc 23533 Evaluation of major and trace elements in medicinal plants2016 - SILVA, PAULO S.C.; FRANCISCONI, LUCILAINE S.; GONÇALVES, RODOLFO D.M.R.This study presents the elemental concentration results obtained from 59 medicinal plants used in Brazil, determined by instrumental neutron activation analysis (INAA), inductively coupled plasma-optical emission spectrometry (ICP OES) and cold vapor atomic absorption spectrometry (CV AAS). The selected plant species were chosen from the Brazilian National Agency for Sanitary Vigilance (ANVISA) list of herbs recommended for utilization by the Public System of Health in Brazil (SUS). The results showed that high levels of foreign matter were found in almost 50% of the analyzed samples. The concentration of the elements varied in a wide range, although, generally in accordance with values found in literature. High concentrations of Ba, Cr, Fe, Hg, Se and Ni were found in some samples. The enrichment factor indicated that potentially hazardous elements can be accumulated mainly in the bark of the plants, possibly indicating an anthropogenic contribution.Artigo IPEN-doc 21139 Micronutrients evaluation in Bidens pilosa L., a plant applied diabetes treatments2015 - GONCALVES, RODOLFO D.M.R.; SILVA, PAULO S.C. daResumo IPEN-doc 20570 Instrumental neutron activation analysis of Bidens polosa, a medicinal plant used for diabetes treating2014 - GONCALVES, RODOLFO D.M.R.; SILVA, PAULO S.C. daResumo IPEN-doc 18654 Mineral elements determination in medicinal plants2012 - SILVA, PAULO; FRANCISCONI, LUCILAINE S.; GONCALVES, RODOLFO D.M.R.Artigo IPEN-doc 19430 Chemometric evaluation of trace elements in brazilian medicinal plants2013 - SILVA, PAULO S.C. da; FRANCISCONI, LUCILAINE S.; GONCALVES, RODOLFO D.M.R.Artigo IPEN-doc 19427 Rare earth elements determination in medicinal plants neutron activation analysis2013 - GONCALVES, RODOLFO D.M.R.; FRANCISCONI, LUCILAINE S.; SILVA, PAULO S.C. daArtigo IPEN-doc 19234 Determination of essential elements in herbal extracts by neutron activation analysis2013 - FRANCISCONI, LUCILAINE S.; GONCALVES, RODOLFO D.M.R.; SILVA, PAULO S.C. daArtigo IPEN-doc 17135 Inorganic contituents in herbal medicine by neutron activation analysis2011 - GONCALVES, RODOLFO D.M.R.; FRANCISCONI, LUCILAINE S.; SILVA, PAULO S.C. da
