. Increased synthesis of secondary metabolites in the culture of bearded roots of Hyssopus officinalis L

Abstract

The research evaluates the effect of amino acids (phenylalanine and tyrosine) on the growth and content of biologically active substances in the culture of bearded roots of Hyssopys officinalis. The study of the effect of amino acids on the growth of raw biomass of bearded roots of H. officinalis showed that when phenylalanine and tyrosine were introduced into the nutrient medium at a concentration of 1 μM, the maximum increase in biomass was observed. The content of biologically active substances in the bearded roots of H. officinalis, such as phenolic compounds, flavonoids, hydroxycinnamic acids and the antioxidant activity of extracts, were higher when tyrosine was introduced into the nutrient medium compared with phenylalanine supplements.
