    (جامعة الوادي - University of Eloued, 2020-08-31) Ghadbane, Mouloud; Bounar, Rabaha; Rebbas, Khellaf
    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.

    (جامعة الوادي - University of Eloued, 2020-12-31) rabihat, eadaad; Bounar, Rabah; Ghadbane, Mouloud; Chermat, Sabah; Rebbas, Khellaf
    The ecodendrological study, on 35 plots were sampled in the Alep pine formation of the Ain Hamda Tizi N’bechar forest at the rate of one plot per station and in each plot a Phytoecological floristic survey was carried out. Concerning the species of the floral procession of the pine forest, there are 19 medicinal species, belonging to 13 families and 20 genera. This medicinal potential must be protected and preserved; it is in this context that this study is based on the knowledge of the factors which influence the distribution and the distribution of these species within the framework of a good rational management in support of the local and sustainable development of the local population through valuation.
