This natural substance is extracted by using different solvents (aqueous, ethanolic, and hexane). The evaluation of the antimicrobial activity has only dealt with alkaloids. The antimicrobial effect of alkaloids is evaluated on several microorganisms. It has been tested on eight bacterial strains. The extract has been studied by using two yeasts. Finally, three molds have been studied. It should be noted that these agents are characterized by a high frequency of contamination and pathogenicity. Through this study, we note that Staphylococcus aureus, Saccharomyces cerievisae and E. coli are very sensitive in respect of the ethanol extract. Pseudomonas aerogenosa and Penicillium sp. are resistant to this extract. The other microorganisms are moderately sensitive. The study of the antimicrobial activity of different extracts of the Harmel has shown an optimal activity with the ethanol extract. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peganum%20harmala%20L." title="Peganum harmala L.">Peganum harmala L.</a>, <a href="https://publications.waset.org/abstracts/search?q=seeds" title=" seeds"> seeds</a>, <a href="https://publications.waset.org/abstracts/search?q=alkaloids" title=" alkaloids"> alkaloids</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria" title=" bacteria"> bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=fungi" title=" fungi"> fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=yeast" title=" yeast"> yeast</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a> </p> <a href="https://publications.waset.org/abstracts/1737/the-antimicrobrial-effect-of-alkaloids-harmin-harmalin-extracted-from-peganum-harmala-l-seeds-in-the-south-of-algeria-bousaada" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1737.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">400</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Antimicrobial Activity of Oil Extracted from the Almonds of the Fruits of Argania spinosa in the West of Algeria (Mostaganem)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nassima%20Behidj-Benyounes">Nassima Behidj-Benyounes</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadjiba%20Chebouti"> Nadjiba Chebouti</a>, <a href="https://publications.waset.org/abstracts/search?q=Thoraya%20Dahmane"> Thoraya Dahmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Amina%20Henni"> Amina Henni </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work examines the study of the antimicrobrial effect of oil extracted from the seeds of Argania spinosa L.
