The aim of the study was to determine antimicrobial activity of rhaponticum and shrubby cinquefoil extracts.
Material and Methods. Ethanol extract from the leaves of rhaponticum (Rhaponticum carthamoides D.C. Iljin) and shrubby cinquefoil (Potentilla fruticosa L.) was produced at the Department of Food Technology, Kaunas University of Technology. The antimicrobial activity of the viscous extract or rhaponticum and shrubby cinquefoil was evaluated using standard microorganism cultures (bacteria Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 33499, Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis ATCC 12459, Bacillus subtilis ATCC 6633, Bacillus cereus ATCC 8035 and fungi Candida albicans ATCC 60193). The minimum inhibitory concentration (MIC) of the examined preparations was determined. Results. Both studied preparations – rhaponticum (Rhaponticum carthamoides D.C. Iljin) and shrubby cinquefoil (Potentilla fruticosa L.) – demonstrated similar antimicrobial activity. The highest sensitivity to the studied preparations was observed in microbes with eukaryotic cell structure: Candida albicans, which is a fungus, and a spore-forming prokaryotic bacterium, Bacillus cereus. The highest resistance was observed in Escherichia coli and Klebsiella pneumoniae.
Conclusions
. The studied preparations – viscous extracts of rhaponticum and shrubby cinquefoil – are substances with antimicrobial activity against gram-positive (Staphylococcus aureus and Enterococcus faecalis) and gram-negative (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Proteus mirabilis) bacteria, spore-forming bacteria (Bacillus subtilis and Bacillus cereus), and fungi (Candida albicans).
