Ecological aspects of preparation and use the medicinal vegetative raw material

Quality of medicinal vegetative raw material depends on the contents of not only biologically active ma-terials, but also of chemical elements. The contents of microcells-biophiles (Mn, Zn, Cu), heavy metals (Pb, Cd, Sb, Hg, Cr, Ni) in wild-growing medicinal plants in Tomsk and Kemerovo oblasts are re-searched. It is established, that concentration of some heavy metals in medicinal plants exceeds tolerance levels. The element chemical compound of plants of the researched territory can be considered as reflec-tance of a biogeochemical situation in regions with disturbed natural biogeochemical cycles of elements.
