Assessment of micro- and macroelements profile of vegetable raw materials with potential antidiabetic effect

Relevance. In the pathogenesis of many diseases, including diabetes mellitus, a deficiency of micro- and macroelements plays an important role. Medicinal plant raw materials (MP) of common blueberries (Vaccinium myrtillus L.) and common beans (Phaseolus vulgaris L.) can accumulate micro and macro elements that are necessary for the correction of the pathology of diabetes mellitus. The aim. Evaluation of the elemental composition of blueberry shoots and common bean valves. Material and methods. In this work, as objects of research, we used shoots of blueberry and common bean valve. Raw materials registered as di-etary supplements were purchased from the pharmacy chain in St. Petersburg. The analysis was performed by inductively coupled plasma atomic emission spectrometry (AES) on an Optima 8000 spectrometer (Perkin Elmer, USA). Results. It was found that the studied medicinal plant was dominated by ions of calcium, magnesium, manganese, aluminum and zinc. However, it is worth noting that bean shells contain fewer trace elements than blueberry shoots, but this type of raw material is characterized by a greater accu-mulation of macronutrients (2 times more calcium, 4.9 times more magnesium). The trace element composition of the bean valves is less pro-nounced in quantitative composition in comparison with blueberry shoots (59 times less manganese, 3.3 times less zinc and 2.5 times less copper). Conclusions. It was possible to find out that the major components are calcium, magnesium, manganese, aluminum and zinc, which, as part of mineral plant complexes, participate in the mechanism of antioxidant and hypoglycemic action of plants.
