The effect of new synthetic pyrazinecarboxamide derivatives on flavonolignan and flavonoid production in S. marianum and O. arvensis was investigated.Compound I 5-(2-hydroxybenzoyl)-pyrazine-2-carboxamide has shown to be an effective elicitor of flavonolignan and taxifoline production in S. marianum culture in vitro.The maximum content of silymarin complex(0.08 %) in calluss culture was induced by 168 h elicitor application of concentration of 1.159x10-4 mol/L. All 3 tested concentrations of compound II N-(2-bromo-3-methylphenyl)-5-tert-butylpyrazin-2-carboxamide increased the flavonoid production in callus culture O. arvensis.
