Pectoral species No. 4: molybdenum, tungsten, lithium, vanadium, titanium and zirconium content

Introduction. In medicinal plants, elements are contained in available biogenic complexes. Ultramicroelements (selenium, cobalt, chromium, molybdenum, lithium and others) enter the human body with water, food, medicinal preparations and participate in various biochemical processes. Unlike macro- and micronutrients, information on the content of ultramicroelements in the complex plant preparations is practically absent. Purpose of the study. Study of pectoral species No.4 and medicinal forms on its basis as a potential source of ultramicroelements in the human body. Material and methods. Objects – pectoral species No.4, its components, dry extract and infusions from them. Elemental analysis was carried out by inductively coupled plasma atomic emission spectrometry on an ICP-AES 720-ES device (Agilent Technologies) with preliminary acid mineralisation. Results. The concentration of ultramicroelements (Mo, W, Li, V, Ti, Zr) in various components and in pectoral species No. 4 varied in the range of 0.48–101.02 mg/kg, the transition of these elements in infusions was 0.39–28.06% of the initial content in raw materials. It was found that the daily intake of molybdenum and vanadium with infusion from the pectoral species can reach respectively 42 and 100% of the daily physiological requirement. Breast collection №4 can be considered as an additional source of ultramicroelements in the human body.
