In this present study, water
and methanol extracts of Cornelian cherry fruits (Cornus mas L.) were
studied for evaluating of antioxidant and
antimicrobial properties. The antioxidant properties were evaluated by
determination of 2,2-Diphenyl-1-picrylhydrazyl (DPPH)
radical scavenging ability and lipid peroxidation inhibition activity. Also
total phenolic contents of the extracts were detected by Folin method. The
extracts of the fruits have antioxidant potential. The DPPH radical scavenging
activity was higher in water extract (36.6 %) than the methanol extract (30.6
%). Unlike, methanol extract of fruits have more activity (18.9 %) than water
extract (16.7 %), also with higher phenolic compound contents. Antimicrobial
activities of above extracts were also tested against 93 clinical isolates of
human pathogenic strains belonging to 5 bacteria (Entorobacter aerogenes, Escherichia
coli, Proteus mirabilis, Pseudomonas
aeroginosa, Staphylococcus aureus) and 5 yeast species (Candida albicans, Candida glabrata, Candida
krusei, Candida parapisilosis, Candida tropicalis) by disk-diffusion method. The results showed cornelian cherries
are potentially rich source of antimicrobial agents. The most effective
antibacterial activity was expressed by methanol and water extract of cornelian
cherry fruit against S. aureus with 25 mm inhibition zone and 0.156 mg/ml Minimum Inhibitory Concentration (MIC) value. Only methanol extracts of the fruit
have antifungal activity against tested human pathogen clinic isolates.
