Abstract: The invention relates to novel ecologically harmless non-toxic preparations containing plant stress hormones, their derivatives and titanium compounds, which after application by foliar spraying induce in whole intact plants the increase of the content of pharmacologically important secondary metabolites. High activity of these preparations was proved on the increase of contents of bioactive phenolic substances in the extract from the plant Echinacea purpurea L. (Moench.). Increase of the contents of the secondary metabolites in plants may be exploited in agriculture and pharmaceutical industry for the effective production of pharmacologically important substances.
