Elemental composition of Rhaponticum uniflorum (L.)

Rhaponticum uniflorum (L.) is a herbaceous perennial plant of family Asteraceae, it is the most important representative of the ecdysteroid containing plants. The elemental composition of the aerial part and the roots of the Rhaponticum uniflorum (L.) is determined. The elemental composition of 28 chemical elements in aerial part and 26 in roots have been found by the method of emission spectral analysis. The peculiarity of samples is the content of a large number of chemical elements with a range on concentrations for some mathematical orders, including the weight content of the elements of the order of 10 -4-10 -7 g/g of raw materials. The highest content of Si, Ca, Mg, P, and the presence of significant amounts of Al, Fe, Na, Mn, Zn, Sr is observed
