Abstract
Content of conventionally essential microelements (Li, B, Si, Ti, V, Ni) was studied in 21 species of medicinal herbs growing on different kinds of soil in Western Transbaikalia under the ecological phytocoenotic conditions of arid steppe, meadow with insufficient and normal wetting, and meadow bog. The species and ecological specificity of microelement accumulation in plants was determined. Different levels of microelement content in medicinal herbs and the concentrating plant species for Li, B, Si, Ti, V, Ni were established. According to the results of investigation, boron is attributed to the elements with intense absorption from soil, lithium to medium, nickel to weak, vanadium and titanium to the elements of very weak absorption.
