Summary:

The main goal of investigation was antimicrobial activity of herbal extracts from Sedum maximum (L.) Hoffm., Sedum telephium L. received by different methods. Material and Methods. Extractions from the purification of S. maximum (L.) Hoffm. and S. telephium L. obtained by different methods were the object of study. Staphylococcus aureus ATCC 6538P, Pseudomonas aeruginosa ATCC 27835, Escherichia coli ATCC 25922, Candida albicans ATCC 13108 were used as test cultures. Results. The minimum inhibitory concentrations of the investigated flavonoid-containing aqueous solutions of alcohol extracts of the purification were determined for the following test cultures: S. aureus, P. aeruginosa, E. coli. Conclusion. The antibacterial effect of the studied extracts on all strains of bacteria taken in the experiment was detected. The action is most pronounced in relation to S. aureus. Antimycotic activity was not detected.

Summary:

The purpose of the work is to investigate the antimicrobial activity of aqueous alcoholic extract of large stonecrop and purple stonecrop. Material and Methods. The effects of large stonecrop (Sedum maximum (L.) Hoffm.) and purple stonecrop (S. telepium L.) on aqueous solution of alcoholic extracts on Staphylococcus aureus АТС С 209R, Pseu-domonas aeruginosa ATCC 27835, Escherichia coli ATCC 25922 have been studied by the method of double serial dilution followed by seeding on solid culture media. As a result of the work the minimum inhibitory concentrations for all extracts to all the studied cultures have been found. Stonecrop extracts have bactericidal action. Conclusion. Antimicrobial activity has been determined for the extracts of both species for all researched samples of microbial strains.
