Identification of diversity in elements content in medicinal plants belonging to different plant families

Comparison of ICP OES and LIBS Analysis of Medicinal Herbs Rich in Flavonoids from Eastern Europe

“…Its significance is illustrated by the numerous studies to determine the levels of metallic and non-metallic elements, macro-and microelements, essential and toxic elements in plants used medicinally, which have employed a myriad of instrumental analytical techniques. The list includes several spectroscopic methods, for instance, atomic absorption spectrometry (AAS), 1,2 and related techniques such as inductively coupled plasma optical emission spectrometry (ICP OES) 3,4 and inductively coupled plasma-mass spectrometry (ICP-MS), 5 as well as other analytical techniques, e.g., instrumental neutron activation analysis (INAA). 6,7 In recent years, laser-induced breakdown spectroscopy (LIBS) 8 has found application in the analysis of elemental concentrations in samples of natural origin, including plant materials.…”

“…5, 2017 harvest, among other aspects). [20][21][22] Recently, it has been discovered that differences in levels of the same metallic element can be attributed to plant species or botanical family, 1,21 but also in several cases (e.g., Fe level) to origin within a specific region of Europe. 22 In order to interpret the huge databases of results obtained for determining elements in medicinal herbs or in other materials of natural origin, such as tea samples or honeys, multivariate statistical methods are very often required.…”

The analysis of heavy metals content in herbal infusions

“…The mixtures were produced by "Herbapol" -a Polish manufacturer of herbal products. The names of the mixtures involved in the study were as follows: Bobofen (4), Bronchial (8), Cholagoga II (4), Circulosan (4), Diabetosan (4), Gastrosan (8), Infektoten (3), Nervinum (3), Nervosan (6), Normosan (9), Pyrosan (3), Septosan (8), Urosan (9). The number of samples is provided in parenthesis.…”

“…The analysis of Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn content was carried out by means of spectrometer SpectrAA 250 Plus (Varian, Australia) in flame atomic absorption mode [9,10]. The accuracy and precision of the procedure were verified on the basis of 6 …”

“…The group of extracts with low Zn content contained four samples of Normosan (nos. 3,6,7,9), in which the concentration of Zn was between 1.59 and 3.01 mg/kg. On the other hand, the highest content of Zn was observed in the samples of Infektoten 5.95-8.13 mg/kg, Pyrosan 5.84-11.20 mg/kg, and Urosan, except for sample no.…”
