Protective Effect of Cinnamomum tejpata on Lipid Peroxide Formation in Isolated Rat Liver Homogenate

Restrictions on the use of synthetic antioxidants are being imposed because of their toxic properties. The present study is the continuation of a program aimed at investigation on antioxidant activity of extracts from medicinal plants and to identify alternative natural and safe sources of food antioxidant especially from plant origin. Free radicals are involved in more than 50 diseases. Day to day researchers are adding more number of d iseases to the list. In this report the anti-peroxidative effect of alcoholic extract of Cinnamomum tejpata has been studied in rat liver homogenate. Ferrous sulphate has been used as inducer to induce lipid per oxidation. On the basis of results, it could be concluded that TBARS production in normal condition group is very slow and in FeSO4 treated groups, it is very high. Initiation of lipid peroxidation by ferrous sulphate takes place either through ferrylperferryl complex or through OH Radical from Fenton’s reaction. Effect of different concentrations of ferrous sulphate for induction of lipid peroxidation in rat liver homogenate was studied. Dose dependent increase in lipid peroxidation was found. Results revealed that at lower doses the rate of formation of TBARS is slow , which increased with dose. Significant and moderate results were found from 0.40 mM to 0.80 mM of ferrous sulphate.
