Résumé: | The extracts of plants are currently the subject of many scientific researches aiming to exploit their properties antimicrobial appreciated so much in the therapeutic, nutritional, cosmetic, and pharmaceutical fields. In this work, we have study the antimicrobial activity of the extracts namely flavonoids resulting from the Crateagus oxyacatha fruits in two bioclimatic stages (Dellys and Bainem). The determination of the antimicrobial effects on stocks bacterial of Gram(-); Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae and Gram(+) (Bacillus subtilis and Staphylococcus aureus). We have also tested two yeasts; Candida albicans and Saccharomycec cereviciae.
As regards the extract of C. oxyacantha of the area of Bainem, one announces that E. Coli is slightly sensitive to the extract of C. Oxyacantha. However S. aureus and B. subtilis have a strong sensitivity to this extract. Whereas the other bacteria are fairly sensitive.
With regard to yeasts, one notices that S. cerevisiae is slightly resistant to the extract.
This solution has an inhibiting effect on C. albicans.
Concerning the extract of C. oxyacantha of the area of Dellys, one notes that E. Coli is slightly sensitive to the extract of C. Oxyacantha. However S. aureus and B. subtilis have a strong sensitivity to this extract. Whereas the other bacteria are fairly sensitive.
With regard to yeasts, one notices that S. cerevisiae is slightly resistant to the extract.
This extract has a strong inhibiting effect on C. albicans.
Through this study, one notices clearly the sensitivity of bacteria Gram-plus compared to the bacteria Gram-for the two areas. |
