Item Antimicrobial And Antioxidant Activity Of Methanol Extract Of Echinophora Spinosa L. From Jijel, Algeria(جامعة الوادي - University of Eloued, 2020-08-31) Ghadbane, Mouloud; Bounar, Rabaha; Rebbas, KhellafIn 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.Item The Effects Of The Fertil Verde Fertilizer On The Growth And Yield Of Chili Pepper (capsicum Annuum L) In Southern Algeria(جامعة الوادي - University of Eloued, 2020-08-31) Ghemam Amara, Djilani; Kherraz, Khaled; Alia, Zeid; Chamsa, Ahmed Khalifa; Laouedj, Hacene; Senoussi, Mohammad MouradA field experiment was conducted on a private farm in El Oued State of Algeria to study the efficiency of using Fertil Verde as a fertilizer by foliar spry on hot pepper seedlings. The treatment by Fertil Verde increased all growth. The increase was significant in the number of main and secondary stems, the size of the leaves, and the weight of the dry leaves. While, the weight of the wet leaves did not significantly increase. Moreover, the use of Fertil Verde has led to a significant increase in the yield qualities of the plant: the weight and shape of the fruits, fresh yield of the plant, the content of pigment, and the size of the plant. Thus, the combination of fertilizing is common and Fertil Verde is a promising low-cost option in the production of high yields.Item Effects Of Extraction Methods On Total Polyphenols, Free Radical Scavenging And Antibacterial Activity Of Crude Extracts Of Cleome Arabica L. Growing In Oued Souf Region(جامعة الوادي - University of Eloued, 2020-08-31) Chouikh, Atef; Rebiai, Abdelkrim; Aref, Mahdia; Heded, Mounira; Adjal, El Hadda; Alia, FatmaThis study aims to phytochemical study, antiradical scavenging and antibacterial Activity of the extracts of Cleome arabica L. from the region of Oued Souf (East South Algerian). The crud extracts two methods obtained methanolic were maceration (EM) and ultra-sound (EU). The yields were: 8.95% and 9.60%, respectively. The quantitative estimation of total polyphenols is 11.57 mg EAG/g Ex (EM) and 13.46 mg EAG/g Ex (EU). The flavonoids contents in (EM) and (EU) are respectively 5.48 and 6.19 mg EQu/g Ex. the anti-free radical activity in the extracts at (concentration 0.1mg/ml) showed a great capacity to scavenge of the DPPH• radical and the percentage of inhibition was 41% in (EM) and 60.67 % in (EU). The results of the antibacterial activity of two bacterial strains: Escherichia coli and Staphylococcus aureus, revealed that Cleome arabica L. has a significant effect on the two strains with inhibition zones variable from 0 to 12 mm for Escherichia coli and 0 to 13 mm for Staphylococcus aureus.Item Evaluation Of The Anti-anemic Activity Of Date Syrup In Wistar Rats(جامعة الوادي - University of Eloued, 2020-08-31) Touhami, Laiche Ammar; Ghemam Hamed, Amina; Badi, SalimaThe main objective of this study is to determine the effect of food intake of date syrup on the treatment of anemia. First, we used 3 samples of dates from different regions for the preparation of the syrup. We have studied certain criteria (physical, chemical, biochemical, microbiological); where the results showed that the prepared date syrup has a good hygienic quality, and of remarkable nutritional quality due to its ideal content with many properties, such as carbohydrate and protein content. To evaluate the anti-anemic properties of date syrup in rats, anemia is induced by a food having an iron deficiency. Date syrup, prepared from Djamaa dates, was administered by gavage of anemic rats at doses of 1000 mg / kg / day and 2000 mg / kg / day resulting in an increase in hemoglobin, red blood cell count, hematocrit and serum iron. Thanks to the results obtained, date syrup can be classified among the foods that help fight iron deficiency anemia.Item Boulaares, ISlam. Characterization And Acute Toxicity Evaluation Of The Mgo Nanoparticles Synthesized From Aqueous Leaf Extract Of Ocimum Basilicum L(جامعة الوادي - University of Eloued, 2020-08-31) Derouiche, Samir; Guemari, Imane Yousra; Boulaares, ISlamThe aim of this study was to prepare magnesium oxide nanoparticles (MgONPs) using aqueous leave extract of Ocimum basilicum L. and to evaluate their acute toxicity. The characteristics of biosynthesized MgO powder was analyzed by UV–Vis spectroscopy, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The acute toxicity test of MgONPs was applied in Wistar albino rats with different concentration. Results showed that the broad bell-shaped spectrum band was obtained by UV–Vis spectroscopy indicates the formation of MgO. The SEM images provided further insight into the shape and size of MgO which to be ranging under 440 nm. Fourier transform infrared (FTIR) spectroscopy detected the vibration of the Mg─O bond that indicate the presence of magnesium oxide nanoparticles (MgO). In this study, the toxicity test showed no mortality or behavioral change in low dose of MgNPs (250 mg / kg b.w) but we observed that 50% of rats have died when treated with high dose of MgNPs (500 mg/kg b.w.). This study confirmed that aqueous extract of Ocimum basilicum L. has potential properties as biocatalyst for the biosynthesis of MgONPs without any toxicity under dose 250 mg/kg in rats.
