Aim. To obtain a plant tissue culture of S. baicalensis as a possible source of biologically active compounds (BAC) with a wide range of pharmacological action. Methods. Plant tissue culture, photocolorimetric method, reversed-phase high performance liquid chromatography (HPLC) method. Results. Two stably productive plant tissue culture strains (16SB3 and 20SB4) of S. baicalensis were obtained from fragments of roots seedling on a specially developed agar nutrient medium 5С01. The yield of dry biomass from 1 liter of this medium per passage (21st day of growth) for strain 16SB3 is 25–30 g, for strain 20SB4 – 30–40 g. The total content of flavonoids in dry biomass was in terms of routine for strains 16SB3 and 20SB4 – 0.6–0.9 and 0.7–0.9 mg/g, respectively, and the yield of flavonoids – 18–27 and 21–36 mg/l of nutrient medium, respectively. BAC typical for plants in nature, in particular, flavonoids vogonin, baikalein, neobaikalein, skulkapfavon and their derivatives, were found in the studied biomass of both strains. Conclusions. It was found that the biomass of the two strains of S. baicalensis plant tissue culture accumulated the same BAC, in particular, flavonoids, as do plants in natural conditions. The resulting plant tissue culture is promising as a possible source of Baikal skullcap BAC.
