Free Radical Scavenging Activity of Viola odorata Water Extracts

摘要

Free radicals cause the oxidation of biomolecules (e.g., protein, amino acids, lipid, and DNA), which leads to cell injury and death. The cytotoxic effect of free radicals is deleterious to mammalian cells. Fresh flowers of spicy violet, Viola odorata (Violaceae), were collected from two different locations—Vranje and Belgrade—in Serbia. The flowers were extracted with water and the suspension filtered and lyophilized for 3 days. Extracts were evaluated on their antioxidant potential using scavenging of 2,2-diphenyl-1-picrylhydrazyl radical. Results showed that water extracts of flowers from both locations possess concentration dependent free radical scavenging activityView full textDownload full textKeywordsVranje, Belgrade, DPPHRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10496475.2011.603588
