ABSTRACT. Relevance. In plants, these elements are in biologically available forms that are easily absorbed into human body. However, herbal preparations are not considered as a source of mineral elements.
The aim of this study – study of the content of manganese, zinc and copper in breast collection No. 4 and its components sold in the Russian Federation was studied.
Materials and methods. The object of the study is the breast collection No. 4 produced by JSC "Krasnogorskleksredstva" and its components: chamomile flowers, calendula flowers, peppermint leaves, marsh shoots, licorice roots, violets grass. The content of elements in medicinal plant raw materials and in its infusions was measured by atomic emission spectrometry.
Results. It was found that in breast collection No. 4, the content of Cu, Mn and Zn varied in the range of 8.59–282.14 mg/kg, and the transition to aqueous extracts was 33.6–44.8%. The transition of trace elements from the collection to the infusion was higher than from individual components. The possible daily intake of Cu, Mn and Zn with aqueous extraction was 23.26; 0.80; 2.28 mg/day, respectively.
Conclusion: Our research has shown that breast collection No. 4 can be considered as an additional source of trace elements.
