Although multiple mechanisms are involved, generation of free radicals is the most commonly postulated mechanism. Therefore, free radical scavengers are considered as potential therapeutic agents. As <jats:italic>Murraya koenigii<\/jats:italic> leaves are a rich source of flavonoids and phenols, they have the ability to scavenge free radicals effectively. Therefore, the objective of this study was to investigate the cardioprotective potential of <jats:italic>Murraya<\/jats:italic> leaf extract against doxorubicin\u2010induced cardiotoxicity in rats. Rats were randomly divided into five groups with 10 animals in each group. Doxorubicin was administered intraperitonially at 18\u2009mg\/kg while lyophilized plant extract was administered orally at 2\u2009g\/kg. Dexrazoxane, at 180\u2009mg\/kg, was used as the positive control. Cardiac damage of doxorubicin control was evident with a significant increase (<jats:italic>p<\/jats:italic> &lt; 0.05) in cardiac troponin I, NT\u2010pro BNP, AST, and LDH compared to the normal control. Plant\u2010treated group showed cardioprotective effect by significantly reducing (<jats:italic>p<\/jats:italic> &lt; 0.05) all of the above parameters compared to doxorubicin control (<jats:italic>p<\/jats:italic> &lt; 0.05). Increased oxidative stress in doxorubicin control was evident with a significant reduction in reduced glutathione, glutathione reductase, glutathione peroxidase, total antioxidant capacity, superoxide dismutase, and catalase activity and a significant increase in lipid peroxidation compared to the control. Interestingly, treatment with <jats:italic>Murraya<\/jats:italic> leaf extract showed a significant increase in all of the above antioxidant parameters and a significant reduction in lipid peroxidation by showing an antioxidant effect. A significant increase in myeloperoxidase activity confirmed the increased inflammatory activity in doxorubicin control group whereas plant\u2010treated group showed a significant reduction (<jats:italic>p<\/jats:italic> &lt; 0.05) which expressed the anti\u2010inflammatory effect of <jats:italic>Murraya<\/jats:italic> leaf extract. Doxorubicin\u2010treated group showed histological evidence of extensive damage to the myocardium while plant\u2010treated group showed a preserved myocardium with lesser degree of damage. Pretreatment with <jats:italic>Murraya<\/jats:italic> leaf extract may replenish cardiomyocytes with antioxidants and promote the defense against doxorubicin\u2010induced cardiotoxicity.<\/jats:p>","DOI":"10.1155\/2020\/6023737","type":"journal-article","created":{"date-parts":[[2020,3,16]],"date-time":"2020-03-16T23:31:15Z","timestamp":1584401475000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Cardioprotective Potential of <i>Murraya koenigii<\/i> (L.)
