The microscopic analysis doesn＇t allow a differential identification of the species. The results of aromatogram by the incorporation method of Muller-Hinton on solid medium, showed a significant antimicrobial activity （method Duraffourd,1987） of the extracts, infusion, and the active substances towards bacterial strains, essentially those recognized as antibiotic resistant （Staphylococcus, Acinetobacter, Pseudomonas, Enterobacter, Citrobacter）; the results obtained indicate that the most efficient antibacterial activity was obtained with the pod infusion, the seed extract and the flavonoids. The raw extract has an important antifungal activity on Candida albicans. This could open opportunities for using this species in the treatment of urinary, respiratory, intestinals and cutaneous infections, and as a disinfecting additive on nosocomial area.展开更多

There is an important quantity of essential oils in the flowers; the interest of this study is that this species remains until then it is not very known. The results of Aromatogram method by incorporation of Mtiller-Hinton on solid medium, showed a significant antimicrobial activity （method of Duraffourd, 1987） of the infusion and the ethanolic extract; the infusion of stems and flowers is indeed much more active on Echerichia coli, Citrobacter, Enterobacter, Staph aureus and Staph epidermidis, such as flowers extracts demonstrate an important antimicrobial activity on Staph aureus, Staph epidermidis, Streptococcus, Pseudomonas and Acinetobacter recognized as antibiotic resistant. This could give opportunities for using this species in the treatment of diverse infections and as a disinfecting additive on nosocomial area. The valorization, preservation and sustainable use ofAmmoides verticillata require the protection of its habitats.展开更多
