Projects

LignoQuat Antibacterial Technologies
Year: 2025 - 2026
Evaluation of antioxidant and antibacterial activity of plant extracts
Year: 2022 - 2025
The aim of this project is to apply an innovative approach to the study of the antioxidant / antibacterial properties of plant extracts used in folk medicine using structure-based fractionation, characterization by multi-instrumental methods and evaluation of activity against Gram-negative bacteria (E. coli and B. burgdorferi).
Study of Estonian propolis
Year: 2024 - 2024
The aim of the study is to determine the chemical composition of 30 propolis samples collected from different counties of Estonia and to study their antioxidant and antibacterial effects.
