Extracting the active compounds and estimate the effectiveness of antioxidant in Medicinal plants desert Limoniastrum guyonianum (Ze茂ta) from South Algeria. Methods: Total phenolic content and total flavonoid content using Folin-Ciocalteu and aluminum chloride colorimetric methods, respectively. The total antioxidant capacity was estimated by the following methods: DPPH (1.1-diphenyl-2-picrylhydrazyl radical) and reducing power assay. Results: Phytochemical screening of the plant part reveals the presence of phenols, saponins, flavonoids and tannins. While alkaloids and Terpenoids were absent. The acetonic extract of L. guyonianum was extracted successively with ethyl acetate and butanol. Extraction of yield varied widely in the L. guyonianum ranging from (0.9425 %to 11.131%). The total phenolic content ranged from 53.33 mg GAE/g DW to 672.79 mg GAE/g DW. The total flavonoid concentrations varied from 5.45 to 21.71 mg/100g. IC50 values ranged from 0.02 卤 0.0004 to 0.13 卤 0.002 mg/ml. All extracts showed very good activity of ferric reducing power, the higher power was in butanol fraction (23.91 mM) more effective than BHA, BHT and VC. Conclusions: Demonstrated this study that the acetonic extract of L. guyonianum contain a considerable quantity of phenolic compounds and possess a good antioxidant activity. Can be used as an easily accessible source of Natural Antioxidants and as a possible food supplement and in the pharmaceutical industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=limoniastrum%20guyonianum" title="limoniastrum guyonianum">limoniastrum guyonianum</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolics%20compounds" title=" phenolics compounds"> phenolics compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoid%20compound" title=" flavonoid compound"> flavonoid compound</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a> </p> <a href="https://publications.waset.org/abstracts/38407/evaluation-of-antioxidants-in-medicinal-plant-limoniastrum-guyonianum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38407.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">348</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> Extracting the Antioxidant Compounds of Medicinal Plant Limoniastrum guyonianum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Assia%20Belfar">Assia Belfar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hadjadj"> Mohamed Hadjadj</a>, <a href="https://publications.waset.org/abstracts/search?q=Messaouda%20Dakmouche"> Messaouda Dakmouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Ghiaba"> Zineb Ghiaba</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Belguidoum"> Mahdi Belguidoum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: This study aims to phytochemical screening; Extracting the active compounds and estimate the effectiveness of antioxidant in Medicinal plants desert Limoniastrum guyonianum (Ze茂ta) from South Algeria.

Results: Phytochemical screening of the plant part reveals the presence of phenols, saponins, flavonoids and tannins. While alkaloids and Terpenoids were absent. The Methanolic extract of L. guyonianum was extracted successively with ethyl acetate and butanol. Extraction of yield varied widely in the L. guyonianum ranging from (1.315 % to 4.218%). butanol fraction had the highest yield. The higher content of phenols was recorded in butanol fraction (311.81 卤 0.02mg GAE/g DW), the higher content of flavonoids was found in butanol fraction (9.58 卤 0.33mg QE/g DW). IC50 of inhibition of radical DPPH in ethyl acetate fraction was (0.05 卤 0.01碌g/ml) Equal effectiveness with BHT, All extracts showed good activity of ferric reducing power, the higher power was in butanol fraction (16.16 卤 0.05mM).
