Résumé
Contexte
Les substances phytochimiques sont des composés naturels bioactifs qui agissent comme des agents protecteurs contre le stress chez les plantes. Ces composés phytochimiques pourraient également présenter d’autres activités biologiques telles que l’activité antibactérienne.
Objectif
L’objectif de ce travail est l’étude de l’effet antibactérien des extraits aqueux et hydroalcooliques préparés à partir des feuilles de Thymus vulgaris, d’Aloysia triphylla, de Pistacia lentiscus, d’Olea europaea et des graines de Trigonella foenum-graecum sur quelques bactéries pathogènes responsables de gastroentérites.
Résultats
Les résultats de l’effet antibactérien ont montré une activité modérée contre les souches étudiées avec des diamètres des zones d’inhibition allant de 07,00 ± 0,8 jusqu’à 16,00 ± 1,0 mm pour les extraits aqueux et variant entre 07,00 ± 0,9 et 13,00 ± 1,0 mm pour les extraits hydroalcooliques.
Conclusion
Cette étude confirme donc la possibilité d’utiliser ces plantes ou ses composants dans la prévention de plusieurs pathologies comme les gastroentérites.
Abstract
Background
Phytochemicals are natural bioactive compounds that protect plants against the stress. These phytochemicals may also have other biological activities like, antibacterial activity.
Objective
The objective of this work is to study the antibacterial effect of aqueous and hydro-alcoholic extracts prepared from Thymus vulgaris, Aloysia triphylla, Pistacia lentiscus, Olea europaea leaves and Trigonella foenum-graecum seeds on some pathogenic bacteria responsible for gastroenteritis.
Result
The results obtained from the antibacterial effect showed a moderate activity against the strains studied with a diameters of inhibition zones ranging from 07.00 ± 0.8 to 16.00 ± 1.0 mm for aqueous extracts and vary between 07.00 ± 0.9 and 13.00 ± 1.0 mm for hydro-alcoholic extracts.
Conclusion
This study confirms the possibility of using these plants or components in the prevention of several diseases like, gastroenteritis.
