“…In turn, the amount of copper recorded in our study (0.42 to 1.85 mg·100 g −1 ) was similar to that reported by other authors (from 0.72 to 1.54 mg·100 g −1 ) [14, 20]. …”

“…The weakest transfer into the herbal tea was noted for iron (on average less than 6 %). Similar results were reported by other authors [2, 14, 20]. For manganese and calcium, the average degree of extraction was higher than that recorded by the abovementioned authors.…”

“…The results were close to those reported by other authors [14, 20, 22]. Similarly, in the case of manganese, the presence of Yerba mate in the composition may have contributed to the higher amounts of this element in the infusions of herbal teas C, B, and E (0.33–0.30 mg·100 ml −1 ).…”

“…0.008 and 0.011 %, respectively. In the study reported by Łozak [20], in which the mineral composition of slimming herbal tea was analysed, the concentrations of cadmium and lead in all samples were below the EC maximum level for Cd and Pb. In this study, the levels of these heavy metals were not determined.…”

“…Such a span can be connected with the rich ingredient composition of the studied products. Other authors reported less diverse results concerning the content of these elements in slimming teas [14, 20]. In the infusion of herbal tea B, with Yerba mate ( Ilex paraguariensis A.…”

The study aimed at determination of the mineral composition of slimming herbal teas and estimation of the coverage of their total intake with infusions in women’s daily diet. The content of Na+, K+, Ca+2, Mg+2, Zn+2, Cu+2, Fe+2, and Mn+2 was determined in infusions and mineralisates obtained from the slimming herbal teas. Among macroelements, the highest content was recorded for Ca—on average 3.73 mg·100 ml−1 in its infusion. Mn was a microelement with the highest concentration amounting to 0.20 mg·100 ml−1 in the infusion. The investigations revealed that, referring to the dietary reference intakes (DRIs), weight loss herbal infusions cover the recommended daily intake of manganese for women to the highest extent (on average 54 %), which suggests that they can be a major source of this microelement for the organism. Herbal teas only to a slight extent (to approx. 4 %) covered the recommended daily intake of magnesium, sodium, potassium, iron, zinc, copper, and calcium in the daily diet.

BACKGROUND: Garcinia (Clusiaceae) species are traditionally used as flavoring agents in curries and to cure several human health complications. This study investigated 31 macro, micro, and trace elements in microwave-assisted digested samples of Garcinia cambogia fruit and its anti-obesity commercial products by inductively coupled plasma-optical emission spectroscopy (ICP-OES) and inductively coupled plasma-mass spectrometric (ICP-MS) techniques. The methods were also validated using the coefficient of determination (R 2 ), limits of detection and quantification (LOD, LOQ), precision (CV%), analysis of certified reference materials, spiking recovery experiments, and participation in an accredited laboratory proficiency test organized by Food Analysis Performance Assessment Scheme (FAPAS). RESULTS: Quality assurance confirmed that the methods were efficient and in accordance with criteria set by the Association of Official Analytical Chemists (AOAC). In the elemental analysis, the analyzed macro, micro, and trace essential elements were present in appreciable concentrations, which could meet the human nutritional requirements. Traces of toxic elements were within safe limits. CONCLUSION: From the results of the current study, the fruit and its commercial products could be considered potential sources of mineral elements without posing any threats to consumers.
