Bacopa monnieri (Water hyssop) is a hydrophyte occurring in Asia and the southern US states. This plant is known in India as Brahmi and has been used in Ayurvedic medicine for 5,000 years as sedative, supporting the treatment of insomnia and improving cerebral circulation. For the biological effect in this species are responsible triterpenoids saponins – bacosides. The aim of the study was to obtain the biomass of B. monnieri shoot in vitro cultures, and then evaluating the biomass growth and content of zinc. B. monnieri derived from in vitro culture on Murashige-Skoog medium (MS) and on the same medium, but enriched in organic additives and elements may be a good source of Zinc for the human body. The experiment was also conducted on the commercial formulations containing B. monnieri. For the determination of zinc ions DP ASV method was used. It was found that the use of highly mineralized water (mineral water “Stefan” – Spa Szczawnica) for extraction of B. monnieri biomass from in vitro culture provided the highest concentration of zinc in the material and for the biomass from MS medium with the addition of As (163.52, and 167.23 mg/mL, respectively). The lowest ontent
was found in B. monnieri biomass from MS medium supplemented with serine, and the capsules product (13.54 and 14.57 mg/mL). For extracts of B. monnieri biomass from MS medium enriched with Zn salts into digestive juices the highest concentration of zinc was determined in gastric juice (6.88 mg/mL).
