The aim of the work is to experimentally determine the optimal parameters for obtaining a tincture of rhizomes with roots of Sanguisorba officinalis and to investigate its antimicrobial and antioxidant activity.Materials and methods. Rhizomes with roots of Sanguisorba officinalis were harvested in autumn 2019. When establishing the optimal parameters of the technology of obtaining tincture, the evaluation criterion was the number of the sum of polyphenols and the amount of hydroxycinnamic acids, which were determined by spectrophotometric method according to the methods of the State Pharmacopoeia of Ukraine 2.0. Antimicrobial activity was studied by agar diffusion and serial dilutions, antioxidant – in vitro using a stable radical 2,2-diphenyl-1-picrylhydrazyl (2,2-diphenyl-1-picrylhydrazyl – DPPH).Results. The optimal parameters for obtaining a tincture of rhizomes with roots of Sanguisorba officinalis was extraction method maceration at room temperature, raw material-finished product ratio 1:5, time 48 hours, extractant 50 % ethyl alcohol, the number of polyphenols, and the number of hydroxycinnamic acids in terms of dry raw materials not less than 4.0 % and 1.5 % respectively. The resulting tincture exhibits antimicrobial activity against microorganisms Bacillus subtilis ATCC 6633 (growth retardation 26.40 ± 1.04 mm), Staphylococcus aureus ATCC 25923 (growth retardation 24.60 ± 0.68 mm) and Pseudomonas aeruginosa ATCС 27853 (growth retardation 23.60 ± 0.68 mm) and at a dose of 0.02 ml showed antioxidant activity at the level of 70 %.Conclusions. The parameters of obtaining a tincture of rhizomes with roots of Sanguisorba officinalis were determined and its antimicrobial and antioxidant activity was studied.
