In vitro EFFICACY OF EXTRACTS OF Arctostaphylos uva-ursi L. ON CLINICAL ISOLATED Escherichia coli AND Enterococcus faecalis STRAINS
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...
متن کاملComparative study of the leaf volatiles of Arctostaphylos uva-ursi (L.) Spreng. and Vaccinium vitis-idaea L. (Ericaceae).
The first GC and GC/MS analyses of the essential oils hydrodistilled from dry leaves of Arctostaphylos uva-ursi and Vaccinium vitis-idaea enabled the identification of 338 components in total (90.4 and 91.7% of the total GC peak areas, respectively). Terpenoids, fatty acids, fatty acid- and carotenoid derived compounds were predominant in the two samples. Both oils were characterized by high re...
