ABSTRACT. Chamerion angustifolium (L.) Holub., the family Onagraceae (kipreyny), is an herbaceous plant that grows abundant in the wild of Eurasia and North America, since the 16th century widely used in fresh and dried form as a medicinal plant in folk medicine, and in fermented form for the preparation of infusions (tea drinks). It is known from scientific publications that 61 elements have been found in the mineral component of this plant, the content of which depends on the area of its growth. At the same time, most works provide results of determination of gross content of elements, on the basis of which many researchers refer to Ch. angustifolium to a possible source of vital human elements. It does not take into account that many of these elements cannot be fully absorbed by the body during digestion. During this work by means of a mass spectrometry method with the inductive and connected plasma (ISP-MS) the maintenance of 25 the elements, most important for the person was studied (Al, B, V, Fe, I, K, Cd, Ca, Co, Si, Li, Mg, Mn, Cu, As, Na, Ni, Sn, Hg, Pb, Se, Sr, P, Cr, Zn). These elements are converted into a water-soluble form in the conventional method of preparing a tea beverage from dry veg-etable raw materials - Ch leaves. angustifolium collected in 2018 in the wild in the territory of the Nizhnevartovsky district of Khanty-Mansi Autonomous District - Ugra, as well as comparison of the obtained results with reference values of standards of adequate daily consumption of human elements. As a result, Ch was found to be in the leaves. angustifolium the most important elements for human nutrition are manganese and magnesium, contained in the amount of 3.3%/g and 1.1%/g (respectively) of daily consumption of these elements by adults. This plant raw material is not toxic to humans since the known daily level of human toxicity in Ch leaves. angustifolium as defined will primarily be achieved by manganese (0.33%/g) and potassium (0.22%/g). The remaining elements reach less than 0.1% of the known daily toxicity level, or have no toxic effect on humans at all when ingested with food.
