Evaluation of the content and bioaccessibility of selected metals from barley grass

The evaluation of the content of zinc and copper in plant tissues of barley grass growing on enriched in zinc/copper solutions (sulphate, glycine complex, rutin complex) were studied by inductively coupled plasma mass spectrometry. The highest concentrations of Zn were found in the roots and leaves,...

Description
Summary:The evaluation of the content of zinc and copper in plant tissues of barley grass growing on enriched in zinc/copper solutions (sulphate, glycine complex, rutin complex) were studied by inductively coupled plasma mass spectrometry. The highest concentrations of Zn were found in the roots and leaves, growing on solutions enriched in the rutin-zinc(II) and sulphate solutions. The highest concentrations of Cu were found in the leaves, growing on solutions enriched in the glycine-copper(II) complex solutions. The research showed that the barley accumulates the zinc/copper from the nutrient solution, therefore, in the next step of the investigation the evaluation of bioaccessibility was carried out. The bioaccessibility of copper and zinc were evaluated from the various enriched cultivation solutions by the inductively coupled mass spectrometry coupled with size exclusion chromatography. Plants growing on solutions enriched in the zinc/copper complexes with amino acids (glycine) and flavonoids (rutin) accumulated excessive amounts of these elements in tissues. Additionally, the bioaccessibility is significantly higher than from the plant’s tissues growing on zinc/copper salts solutions.
