Solvent effects on phenolic contents and biological activities of the halophyte Limoniastrum monopetalum leaves Najla Trabelsi, Wided Megdiche, Riadh Ksouri, Hanen Falleh, Samia Oueslati, Bourgou Soumaya, Hafedh Hajlaoui, Chedly Abdelly Details Authors Fields of science Bibliography Quotations Similar Collections Source LWT - Food Science and Technology > 2010 > 43 > 4 > 632-639 Abstract Limoniastrum monopetalum is a traditional medicinal species which leaf infusion exhibits antidysenteric properties against infectious diseases. In this study, ten kinds of leaf extracts were used to examine the effect of extraction solvent system with varying polarities on polyphenol contents and DPPH scavenging activity. Then the superoxide scavenging activity and the reducing power of the most promising solvent extracts were evaluated too. Moreover, the efficiency of the best leaf extract has been investigated against pathogenic bacteria and yeast. Eventually leaf extract was hydrolyzed by acid and the phenolics identified by RP-HPLC. Results showed that phenolic contents and antioxidant activities varied considerably as function of solvent polarity. Leaf extract using pure methanol showed the highest polyphenol content (15.85mg GAE/g DW). Moreover, antiradical capacities against DPPH. https://www.infona.pl/resource/bwmeta1.element.elsevier-269447d9-b3d0-3d1a-bd9a-82c8736a79d4 accessdate=30 December 2015
