The effectiveness of medicinal plants is mainly associated with their active constituents, but one of the major quality problems frequently encountered is their high trace metals content that can be associated to extensive pollution of the environment where medicinal plants grow. Therefore the aim of this research was to evaluate the content of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn and As in selected and frequently used medicinal plants, including chicory, broadleaf, common comfrey and dandelion. The plant material was collected from their wild habitats in the area of highly developed power plant activity during the summer of 2015. Plant analyses were done according to ICP methodology, using ICAP 6300 ICP optical emission spectrometer. The obtained results showed that the content of As, Cd, Co, Mn, Ni and Zn in the investigated medicinal plant species was below the maximum permissible concentration, while in all parts of all studied plants the concentration of Cr was toxic. The toxic concentrations of Cu were determined in root and aerial parts of chicory and common comfrey, and the toxic concentrations of Fe in root and aerial parts of dandelion and broadleaf plantain, and in aerial parts of common comfrey. However, high but not toxic content of Pb was found in aerial parts of chicory. It can be concluded that medicinal plants from the studied growing site are not appropriate for use in alternative medicine and that a determination of trace metals content in these plants must become a standard criterion for evaluation of their quality.
药用植物的有效性主要与其活性成分有关，但经常遇到的主要质量问题之一是其高痕量金属含量，这可能与药用植物生长环境的广泛污染有关。因此，本研究的目的是评估选定且常用的药用植物中镉、钴、铬、铜、铁、锰、镍、铅、锌和砷的含量，这些植物包括菊苣、阔叶车前、聚合草和蒲公英。植物材料于2015年夏季从发电厂活动高度发达地区的野生栖息地采集。采用ICP方法，使用ICAP 6300 ICP光发射光谱仪进行植物分析。所得结果表明，所研究的药用植物物种中砷、镉、钴、锰、镍和锌的含量低于最大允许浓度，而在所有研究植物的所有部位，铬的浓度均具有毒性。在菊苣和聚合草的根和地上部分测定到了铜的毒性浓度，在蒲公英和阔叶车前的根和地上部分以及聚合草的地上部分测定到了铁的毒性浓度。然而，在菊苣的地上部分发现了高含量但无毒的铅。可以得出结论，来自所研究生长地点的药用植物不适用于替代医学，并且测定这些植物中的痕量金属含量必须成为评估其质量的标准标准。
