Accumulation of alkaloids in plants of the family Boraginaceae depending on environmental conditions places of growth

Due to the lack of information on influence environmental factors accumulation pyrrolizidine alkaloids and their content in certain species this family Boraginaceae, aim study was assess level aboveground under-ground parts Symphytum asperum Lepech., S. caucasicum M. Bieb., Echium vulgare L., Pulmonaria mollis Wulfen ex Hornem. depending climatic, orographic edaphic conditions. The localization alka-loids rhizomes with roots, glandular trichomes leaves stems, epidermal cells revealed. phytomass decreases series ˃ Е. , underground P. . At end growing season, an increase a decrease one were noted. An air temperature precipitation contribute roots shoots. correlation between trace elements varies from high (Cu, Zn, Mo) medium (Mn, Pb). results obtained indicate need take into account implementation medicinal collections preparation feed plants.
