In this study, the antioxidant and antimicrobial activities of Echinophora spinosa were investigated. Antimicrobial activity of methanol extracts obtained from Echinophora spinosa was examined using the disc diffusion method. Antioxidant activity of the methanol extracts was examined using the stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging test. Methanol extract of ripe fruits of E. spinosa showed highest total phenolic content (69.17 ± 1.2 µg GAE/mg extract) and the major flavonoid contents (12.122 ± 0.44 µg QE/mg extract) was found in leaves of the plant. In disk diffusion antimicrobial assay, E. spinosa manifested broad spectrum of activity. The largest capacity to neutralize DPPH radicals was found for ripe fruits methanol extract of E. spinosa plant. The results shows that the various parts of E. spinosa extracts promising antioxidant and antimicrobial activities have potential bioactivities due to high content of phenolic and flavonoid compounds.

Plant diversity in Mediterranean coastal dune systems subjected to anthropogenic disturbances

Mediterranean coastal dunes have an undeniable value in terms of floristic diversity as a result of their well-adapted plant species, such as psammophytes and halophytes. Unfortunately, these ecosystems are often disturbed by anthropogenic activities, such as the use of bathing settlements and trampling, the construction of paths or roads, and grazing by livestock. In this paper, these environmental factors were considered to determine their relative influences on several Algerian coastal dune systems undergoing ecological disturbance, by measuring in these systems various ecological gradients. Using ecological indices, multivariate analysis of data, and the analysis of variance, we compared the composition of the flora of 7 study sites that were subjected to various scales and types of disturbances. A total of 83 plant species were identified, reflecting the floristic richness of the sites. They seemed to be unevenly distributed and considerably modified according to environmental and human impact descriptors. The composition, abundance, and distribution of plant diversity are positively correlated with the height and width of the dunes. Regrettably, the floristic diversity of coastal dunes is more and more degraded by disturbance pressures (particularly grazing).

Nous avons établi pour la première fois dans la région de Skikda, les listes (liste actualisée et liste des taxons à rechercher) de la flore endémique et des espèces naturalisées jugées envahissantes en méditerranée, représentant une menace potentielle pour cette flore, en réalisant des prospections au niveau de douze communes. Cela a conduit à l’identification de 64 taxons endémiques dont plus de la moitié se trouve dans la liste actualisée (38 taxons). Ces plantes appartiennent à 26 familles, 46 genres et se répartissent en 50 espèces, 11 sous-espèces et 3 variétés. Les endémiques algéro-tunisiennes sont les plus abondantes (30 taxons). 11 espèces envahissantes en méditerranée sont naturalisées dans notre région dont 5 colonisent des milieux naturels particulièrement riches en espèces endémiques. L’Acacia saligna, Carpobrotus edulis et Opuntia ficus-indica sont les principales espèces menaçantes de cette richesse biologique.
