The Content of Minor Elements in the Breast Collection No. 4

Introduction. Trace elements are an essential part of the human body, but about 80 % of the human population notes an imbalance in their content. Medicinal plants contain minerals in an accessible and digestible form together with biologically active substances. Medicinal herbal preparations are very popular for the prevention and as part of the complex therapy of various diseases. However, information about the content of trace elements in multicomponent medicinal herbal preparations is very limited. Therefore, it is necessary to study the mineral composition, which will allow us to consider plant collections as an additional source of trace elements. Aim. The purpose of our study was to study the content of trace elements (B, Si, Al, Ba, Sr, Ti) in breast collection No. 4, its components and aqueous extracts from them. Materials and methods. The objects of the study were breast collection No. 4, its individual components and aqueous extracts from them. Infusions from the samples were obtained according to the instructions for use on the packaging of a medicinal herbal preparation. The samples were prepared for analysis with a mixture of concentrated nitric acid and water deionized in the Milestone Ethos Up microwave system (Milestone, Italy). The analysis was carried out by atomic emission spectrometry with inductively coupled plasma on the ISP-NPP 720-ES device (Agilent Technologies, USA). Results and discussion. It was found that the concentrations of Si, Al, B, Sr, Ba, Ti in individual components of the collection varied in the range of 2.9–1240 mg/kg, the transition of trace elements to aqueous extracts was 0.4–34.2 %. The content of these elements in breast collection No. 4 was found to be 13.3–920.7 mg/kg, and the degree of extraction the infusion was 3–40 %. Comparative analysis showed that the extraction of B, Al, Ba from the collection into the infusion is 14–58 % higher than from the individual components included in its composition. It has been established that 50 % of boron and 264 % of silicon from the recommended adequate level of consumption in the Russian Federation enters the human body with an infusion from the breast collection No. 4. Conclusion. The study showed that breast collection No. 4 can be considered as an additional source of B and Si in the human body. The concentrations of Al, Sr, Ba, Ti were within the average values of the range of the content of these elements in plants.
