Abstract The potentially toxic metals content was determined in selected plants, used in Traditional Chinese Medicine (Angelica sinensis;Bacopa monnieri, Bupleurum sinensis, Curcuma longa, Cola accuminata, Emblica officinalis, Garcinia cambogia, Mucuna pruriens, Ocimum sanctum, Panax ginseng, Pueraria lobata, Salvia miltiorrhiza, Schisandra sinensis, Scutellaria baicalensis, Siraitia grosvenorii, Terminalia arjuna and Terminalia chebula), and some European herbs (Echinacea purpurea, Hypericum perforatum, Vitis vinifera). Samples were mineralized in a closed microwave system using HNO3 and the concentrations of Cd, Pb, Al, As, Ba, Ni and Sb were determined by ICP-MS method. Some relevant aspects of potential toxicity of metallic elements and their compounds were also discussed. Results of metal content analysis in dietary supplements available on Polish market, containing studied plants, are presented as well. The results were analyzed by principal component analysis (PCA) and cluster analysis. (C) 2014 Elsevier GmbH. All rights reserved.
