Abstract

Objective: The present study was aimed to evaluate the antioxidant activity of methanolic extract of leaves of Leucas zeylanica Linn. by using isolated frog heart as a model.

Method: 1mM  of H2O2 solution in frog Ringer solution was used to induce oxidative stress on isolated frog heart. When ringer solution containing H2O2 perfused to frog heart  preparation, which indicating the induction of oxidative stress on frog heart, this might be due to desitilization of receptors. Cardiac output, heart rate and cardiac arrest parameters were estimated.

Results: The present study results supports that the frog heart model for induction of oxidative stress by H2O2. It shows negative ionotropic and chronotopic effects and the cardiac arrest was produced at 20th minute. In the presence of methanolic extract of leaves of Leucas zeylanica,  the cardiac arrest was observed at  38th minutes i.e. heart was protected longer period that indicates antioxidant activity which was compared with the standard ascorbic acid.

                                  

Conclusion: The results obtained in this work showed that methanolic extract of leaves of  Leucas zeylanica exhibits anti-oxidant activity against H2O2 induced oxidative stress on isolated frog heart model and compared with a standard antioxidant agent (Ascorbic acid).

 

Key words: Frog heart, antioxidant activity, Leucas zeylanica, methanolic extract, oxidative stress.
