Background and Objective: Nowadays,
the increasing use of antibiotics, or failure to comply the recommended dose by the patients, has led
to the development of bacterial resistance to antibiotics. It has resulted in increasing the interest to use more efficient
new anti-microbial compounds without toxicity, such as medicinal plants. The aim of this study was to compare the antibacterial activity of aqueous and ethanolic extracts of Kelussia odoratissima on some pathogenic
bacteria.
Materials
and Methods: In this laboratory study, the antibacterial effect of aqueous
and ethanolic extracts of Kelussia odoratissima
leaves were investigated using pour plate
and disk agar diffusion tests. Minimum Inhibitory Concentration (MIC( and Minimum Bactericidal Concentration (MBC) were also studied using
the Dilution method. Analysis of results was performed using One-way analysis
of variance (ANOVA).
Results: MIC of aqueous and ethanolic extracts for Staphylococcus epidermidis and Streptococcus pyogenes was 32 and 16 mg/ml and for Pseudomonas aeruginosa was 64 and 32 mg/ml, respectively. MBC of aqueous and ethanolic extracts for Staphylococcus epidermidis and Streptococcus pyogenes was 64 and 32 mg/ml and
for Pseudomonas aeruginosa was 128 and
64 mg/ml, respectively. The results of One-way
analysis of variance showed, with increasing concentrations of ethanolic and aqueous extracts, inhibition zone was significantly increased.
Conclusion: The results showed that the
ethanolic extract of Kelussia odoratissima leaves
had greater inhibitory effects on the strains studied in comparison with to aqueous extracts in vitro.
