In vitro EFFICACY OF EXTRACTS OF Arctostaphylos uva-ursi L. ON CLINICAL ISOLATED Escherichia coli AND Enterococcus faecalis STRAINS
نویسندگان
چکیده
Antibacterial activity, total phenolic content and flavonoid concentrations of extracts from the leaves of Arctostaphylos uva-ursi L. were performed. Tested bacterial strains are 20 clinical isolates, including different strains of Escherichia coli and Enterococcus faecalis. The total phenolic content was determined using Folin-Ciocalteu reagent. The concentration of flavonoids in extracts were determined using spectrophotometric method with aluminium chloride. The value of minimum inhibitory concentration (MIC) was in the range from 0.625 mg/mL to 10 mg/mL. The most active plant extracts were aqueous and ethanol extracts. Ethanol extract had the highest amount of the total phenolic content (300.23 mg GA/g) and concentration of flavonoids (73.46 mg RU/g).
