Trends in the content of chemical elements in leaves of Lonicers Caerulea (Caprifoliaceae) in connection with their secondary metabolism in the natural populations of the Altai Mountains

Abstract

SRXRF is used to study trends in the content of macro- and microelements in the assimilation organs of blue honeysuckle in geologically contrasting sectors of the Altai Mountains. The accumulation of flavonoids in the organs of L. caerulea is influenced primarily by Cu, Ni, and Zn, as these trace elements are selectively concentrated by this species. Intensified synthesis of chlorogenic acid and its derivatives is due to a considerable increase in Fe concentration in plant leaves.
