Abstract |
Lobularia maritima (Alyssum maritimum, Brassicaceae), commonly known as sweet alyssum, is an annual ornamental halophyte widely spread along the Tunisian seashore. Lobularia maritima leaf ethanol extract was tested in an experimental model of hepatotoxicity induced by carbon tetrachloride (CCl4). L. maritima extract was found to possess in vitro antioxidant activity by scavenging the DPPH radical (IC50= 45 mu g/mL), reducing/chelating iron ions and inhibiting liver lipid peroxidation induced by FeSO4. The levels of total phenolics and flavonoids were 175 +/- 2.66 mg GAE/g, and 35 +/- 2.88 mg QE/g respectively. Moreover, HPLC analysis revealed six compounds, namely gallic, salicylic, ellagic and ferulic acids as well as catechin and quercetin. A mice model of acute liver injury was successfully established after a single intraperitoneal injection of CCl4, as evidenced by histological analysis, Masson trichrome and Sirius red staining. Compared with the CCl4 intoxicated group, the L. maritima treatment resulted to reduce the liver serum marker enzymes, lipid peroxidation and increased the activities of antioxidant enzymes with further amelioration in the oxidative stress. The present findings discover the therapeutic potentials of L. maritima empowered with promising natural leads for the treatment of oxidative stress associated health disorders by attenuating free radicals, inhibiting lipid peroxidation, and upregulating the tissue-specific antioxidant enzymes. |
