Bacopa monnieri is one of the most interesting plants from the Ayurveda system. The aims of present research were, basing on in vitro shoot culture of B. monnieri, to determine content and to evaluate the influence of physiologically important metabolites on the selected bioelements accumulation in biomass. The most significant increase in biomass production was observed in the culture medium enriched with 0.5 mg/L of anthranilic acid. In this medium also, the highest accumulation of Mg was noted. The highest concentration of iron was determined in B. monnieri in vitro culture enriched with 0.25 g/L of serine. The addition of l-tryptophan, magnesium sulfate, and zinc hydroaspartate caused only a small increase in the accumulation of copper in B. monnieri. Increase in Zn accumulation was obtained in biomass from in vitro culture of B. monnieri with the addition of magnesium sulfate and zinc hydroaspartate. In the case of Na, the maximum level of this element was in biomass from medium enriched with zinc hydroaspartate. Twofold increase in K concentration was obtained in biomass from cultures on medium with addition of serine and magnesium sulfate. The concentrations of Ca in biomass of all studied media were at the similar level.
