“…The decoction and infusion were analyzed directly after filtration [17][18][19]. Their majority mineral contents (K, Mg, Ca, Na, Fe, Mn, Zn and Cu) were determined in triplicate by flame atomic absorption spectrometry (Hitachi Z-6100, Japan) equipped with a multi elemental hollow cathode lamp.…”

Opuntia flowers are a natural source of biologically active compounds and they have been used as medicinal plant for a long time. Despite the various uses reported for the decoction and infusion of these flowers, their characterization has been discarded. In this study, the decoction and infusion prepared from Opuntia ficus-indica were analyzed with respect to their content in minerals and phytochemicals in order to evaluate its nutritional characteristics. The obtained data proved that these preparations are a rich source of minerals mainly K and Ca. Moreover, the phytochemical analysis revealed that they have important polyphenols, flavonoids and tannins contents with the infusion that presented the highest polyphenol levels. LC-MS analyses of decoction and infusion allowed the characterization of 20 phenolic compounds. It is mainly identified by the presence of flavonols glycosides.

Objective: To determine concentrations of essential microelements Fe, Cu, Mn and Zn, as well as toxic metals Pb, Cd, Cr and Co, in three herbal remedies and compare the experimental data obtained with available literature data. Materials and Methods: Elemental compositions of three herbal remedies, Chamomile flowers, Urtica folia (nettle) and Hyperichi herba (St John's wort), grown and produced in Ukraine, were studied by flame atomic absorption spectroscopy. Results: The Fe concentration decreases, as well as the Zn and Mn concentrations, increase in going from nettle through chamomile to St John's wort. The Cu content is virtually independent of the plant type. Statistically significant negative correlations between the element concentrations were found in Fe-Mn and Fe-Zn pairs. The studied samples of St John's wort are more contaminated with Cd than other plants, while the highest Pb content is observed in some samples of nettle. Conclusion: The measured levels of both Pb and Cd still secure against overuse of toxic metals with herbal remedies.

“…Several analytical techniques such as flame atomic absorption spectrometry (FAAS) [6], electrothermal atomic absorption spectrometry (ETAAS) [7], and inductively coupled plasmaoptical emission spectrometry (ICP-OES) [8,9], and kinetic-Spectrophotometry [10] devoted to low-level metals determination, however, their present very high acquisition and operational costs. Spectrophotometry is a well-established analytical technique that provides low cost, simplicity and wide range of applications for aluminium determination in some food samples [11][12][13].…”

2-(3-indolyl) -4,5 di phynyl imidazole(IDPI), was used as a complexing agent in cloud point extraction for the first time and applied for selective pre-concentration of trace amounts of Aluminium. The method is based on the extraction of Aluminium at pH 3.5 by using nonionic surfactant T-X114 and 2-(3-indolyl) -4,5 di phenyl imidazole.(IDPI) as a chelating agent. The adopted concentrations for IDPI, Triton X-114 and HNO3, bath temperature, centrifuge rate and time were optimized. Linearity for Al was obeyed in the range of Al 3+ ion 0.2-20.0 ng mL -1 . The Detection Limit (n=10) 0.013(µg.mL -1 ) for Aluminium ion, and along with enrichment factor of 37 for Aluminium ion, RSD % (n=5) 1.3(µg.mL -1 ) for Aluminium ion was achieved. The high efficiency of cloud point extraction to carry out the determination of analytes in complex matrices was demonstrated. The proposed method was successfully applied to the ultra-trace determination of aluminium in real samples.
