title: [The content of Ca, Mg, Fe and Cu in selected species of herbs and herb infusions].
abstract: The aim of the study was the recognition of the contents and distributions of calcium, magnesium, iron and copper in 6 herb species (matricaria chamomila, tilia cordata, equisetum arvense, melissa officinalis, mentha piperita, hypericum perforatum) and in the herb infusions. The samples were digested using a microwave oven, and the elements concentration was determined by AAS method. The following levels of Ca, Mg, Mg and Cu in the herbs were determined: 6872-19802 mg/kg Ca, 4630-8530 mg/kg Mg, 149.9-415.6 mg/kg Fe and 15.15-24.64 mg/kg Cu. The values of extractions in the infusions of herb were as follows: 16.1-73.8% Ca, 14.4-37.3% Mg, 5.1-9.7% Fe, 13.1-21.8% Cu. This indicates, that a very small part of the iron can be potentially treated as a bioavailable fraction for persons, using plant drugs as infusions. One glass of infusion (250 cm3) contain elements in quantities corresponding to: 0.78-2.61% average daily dietary intake (ADDIs) of Ca, 0.76-1.36% ADDIs of Mg, 0.26-0.38% ADDIs of Cu and only 0.15-0.33% ADDIs of Fe.
