“…The results are given in Tables 4 and 5, and the content of the zinc ions found in these samples are similar to those found in previous publications. 19,20 Table 6 shows a comparison of a number of methods for zinc ion preconcentration using FAAS determination. As observed, our developed method exhibits better or comparable figures of merit, primarily when considering the LOD, sample consumption and sample throughput.…”

In this paper, we describe the synthesis of an ion imprinted polymer (IIP) by homogeneous polymerization and its use in solid-phase to extract and preconcentrate zinc ions. Under optimal conditions (pH 5.0, preconcentration flow rate of 12.0 mL min -1 , and eluted with 1.0 mol L −1 HNO 3 ) this procedure allows the determination of zinc with an enrichment factor of 10.2, and with limits of detection and quantification of 1.5 and 5.0 μg L −1 , respectively. The accuracy of our results was confirmed by analysis of tap water and certified reference materials: NIST 1570a (Spinach leaves) and NIST 1515 (Apple leaves).

“…Due to the importance of heavy metal present in herbs, several studies have been carried out to determine their levels. [4][5][6][7] By comparison with heavy metal, the levels of rare earth elements (REEs) in herb tea receive little concern. Some evidences show that excessive exposure to rare earth oxides (REOs) is harmful to human health such as leukemia.…”

The aim of this study was to determine the sixteen rare earth elements (REEs) in twelve types of popular fl ower herb teas and their infusions consumed in China. Microwave-assisted acid digestion was used for all of the samples, and the contents of these elements were determined by inductively coupled plasma mass spectrometry (ICP-MS). The concentrations of REEs varied from 94.6 to 7492 µg kg -1 among these fl ower samples. Ce was the most abundant elements in all fl ower samples (27.3-3016 µg kg -1). The leached ratios of REEs for each type of tea ranged from 7.3% (globe amaranth) to 29.8% (carnation). The leach ratios of REEs in these fl ower herb teas were at different percentages depending on types of fl owers. The daily intake of rare earth oxides from these fl ower herb tea infusions may not produce any health risks.

“…Many plants have been used as folk remedies after preparation in traditional way such as cooking, infusions or macerations. The therapeutic activity of herbs is associated with the content of biologically active elements and organic compounds of varying structures and remedial powers such as vitamins, alkaloids or tannins [3]. Some of plants have also been used as spices which play a major role in cooking, cosmetics and perfumery [5].…”

Abstract:The purpose of this study was to show relationships among the levels of essential metals (zinc, iron, sodium, magnesium, calcium and potassium) and phenolic acids (caffeic, chlorogenic, ferulic, gallic, rosmarinic and syringic) in commercial herbs (lemon balm, thyme, rosemary, mint, sage and angelica) and spices (caraway, lovage, hyssop and oregano). In the herbs higher quantities of metals and phenolic compounds were found than in spices. All plants contained high levels of calcium, potassium and rosmarinic acid, but low levels of zinc and gallic acid. By using principal component and hierarchical cluster analyses several clusters were identified grouping samples originating from a plant of a particular botanical species. Multivariate analysis has also shown that the contents of phenolic acids had a stronger impact on the scattering of herbs and spices than the metals levels. Furthermore, statistically significant correlations were found between calcium and ferulic, gallic, rosmarinic and syringic acids as well as between zinc and sodium and caffeic acid. This suggests co-operate between these biologically active constituents in metabolic processes occurring in plants.
