abstract = "The antimicrobial activity of methanol extracts of aerial parts of 8 Geranium
L. species (G. macrorrhizum L., G. phaeum L., G. sanguineum L., G. robertianum L.,
G. palustre L., G. pyrenaicum Burm. f., G. columbinum L. and G. lucidum L.) was
tested against 8 standard strains (Staphylococcus aureus, Enterococcus faecalis,
Bacillus subtilis, Escherichia coli, Klebsiella pneumaniae, Pseudomonas aeruginosa,
Salmonella abony and Candida albicans) as well as 10 clinical isolates of E. coli.
Also, total phenolics and tannins were quantified using spectrophotometric Folin-
Ciocalteu method. The extracts exhibited antibacterial and anticandidal activity with
minimal inhibitory concentrations (MICs) between 12.5 and 200 μg/ml. E. faecalis
was most sensitive strain (MIC 12.5-50 μg/ml), especially to G. columbinum and G.
phaeum extracts (MICs 12.5 μg/ml). The determined amounts of total phenolics and
tannins were in the range of 170-534 and 38-386 mg GAE/g of dry extract,
respectively, with the highest content in G. sanguineum extract. However, the
antimicrobial activity was not related to total polyphenolics or tannin content and
further investigation in regard with phenolic profile is needed.",
