“…A deficiency of trace elements could bring on structural and physiological abnormalities, while high levels of those essential trace elements may be harmful to human health [8, 9]. There are many studies reporting on trace elements in medicinal herbs, such as Panax ginseng , Salvia miltiorrhiza , Houttuynia cordata and so on [10–13]. In Dendrobium species, there is one report about the determination of trace elements levels for identifying the cultivation technique of Dendrobium officinale [14].…”

Dendrobium, an important medicinal plant, is a source of widely used herbal medicine to nourish the stomach and treat throat inflammation. The present study is aimed at distinguishing and evaluating three major Dendrobium species by comparing physiochemical characteristics and understanding differences between different growth years in the Ta-pieh Mountains. Polysaccharides and total alkaloids of Dendrobium were determined, and the amino acids and trace elements were determined by UPLC (Ultra High-Performance Liquid Chromatography) and ICP-MS (Inductively coupled plasma mass spectrometry). It can be seen from the results that the polysaccharide content of these three kinds of Dendrobium in different growth years ranges from 249.31 mg·g-1 to 547.66 mg·g-1, and the highest content is in the 3-year-old Dendrobium huoshanense. The total alkaloid content ranges from 0.21 mg·g-1 to 0.54 mg·g-1, and the highest content is also the 3-year-old Dendrobium huoshanense. We determined the amino acid content of these three Dendrobium in different growth years, and we can see that each of the three kinds of Dendrobium contain seven kinds of amino acids required by the human body. We conducted a safety evaluation of the essential trace elements of Dendrobium, and the results showed that the dosage of 12g·d-1 Dendrobium prescribed in China Pharmacopoeia is in accordance with the recommended daily intake of trace elements recommended by the Food and Drug Administration of the United States, and will not cause trace element poisoning. Linear discriminant analysis was carried out on the basis of amino acids and trace elements and confirmed the applicability of multi-elemental analysis for identifying different Dendrobium species.

Medicinal plants can amass chemical elements in their tissues due to their ability to tolerate potentially toxic ions in the environment. The Hypericum perforatum L. plants were cultivated in three regions of West Siberia (Kemerovo, Novosibirsk, Kam lak Village (Altai Republic)). Elemental analysis was conducted by atomic emission spectrometry. Chemical elements extractable with 10% HCl were assayed by atomic absorption spectrometry. The concentrations of Co, Ni, Cu and Zn have been relatively stable. The coefficients of biogeochemical mobility of Cd, Cu and Zn had high rates, which confirm the possibility of accumulation of these elements in H. perforatum. The concentration of chemical elements in extracts (10 % HCl) was increased as well as their total contents, the degree of extraction was highest for K, Ni, Fe, Cu, Mn, Mg (90 % or more), the minimum for Na (20–40 %) and significantly changed in environmentally different habitats.

Total reflection X‐ray fluorescence analysis of elemental composition of herbal infusions and teas

BACKGROUND The elemental composition of herbal infusions and teas has not been sufficiently investigated. It could potentially be used for defining fingerprints for individual herbal / tea infusions, differentiation of botanical families, detecting the influence of packaging, and other purposes. The objective of this study was to determine the elemental composition, including the trace element content, of various herbal infusions and teas by means of total reflection X‐ray fluorescence analysis (TXRF), with a chemometrics approach using principal component analysis (PCA). RESULTS This study determined the elemental composition of various herbal infusions and teas, including trace elements, using total reflection X‐ray fluorescence (TXRF). The methodology for the sample preparation was established, including the multiple‐steepings procedure for the two tea samples (Oolong and Pu‐erh). Data from 29 samples were collected. We hypothesized that the elemental content of infusions could reflect certain features, such as the influence of processing and the type of tea. CONCLUSION A chemometric approach (PCA) was applied, and differences between teas and herbal infusions were found. This was further corroborated by explicit differentiation of one botanical family, Theaceae. The influence of packaging (tea bags) on herbal material was identified. The three types of tea ( Camellia sinensis ) appeared to be separated with PCA, and elemental concentrations in Pu‐erh changed with multiple steepings.
