Abstract

Abstract: In this study, the cardioprotective effects of partially purified phenolic fraction of Kedrostis foetidissima leaves (PFK) were evaluated in isoproterenol (ISO)‐induced myocardial infarction rat model. ISO induction to experimental rats for two consecutive days significantly increased the levels of triglycerides, cholesterol, phospholipids, free fatty acids, low‐density lipoproteins, and cardiac biomarker enzymes, and decreased the levels of high‐density lipoproteins and antioxidant enzyme activity. Pretreatment of experimental rats with PFK for 45 days led to a significant elevation in antioxidant enzyme activity. PFK‐pretreated rats exhibited significantly reduced levels of circulating lipids and cardiac‐specific biomarker enzymes compared to ISO‐treated rats. Thus, the present study demonstrated that PFK ameliorated ISO‐induced cardiotoxicity through the augmentation of the endogenous cardiac antioxidant system, thereby modulating the lipid peroxidation caused by ISO‐induced free radicals, and prevented the myocardial damage, which was confirmed through histopathological analysis. Practical applications: Kedrostis foetidissima is edible medicinal plant and phenolic fraction extracted from the leaves of this plant may help the common man in the protection of heart. The phenolic fraction shows significant antioxidant activity, so this might be referred to as dietary supplement and also helps to develop new pharmaceutical formulations. Abstract : The present study aimed to evaluate the cardioprotective effect of partially purified phenolic fraction from Kedrostis foetidissima leaves (PFK) in isoproterenol (ISO)‐induced myocardial infarction in rats. ISO administration to rats significantly produced cardiotoxicity but at the same time rats pretreated with PFK notably protected the heart from ISO toxicity through restoration of cardiac antioxidant status and altered lipid markers. Hence, this study suggested that supplementation of PFK might protect the heart and will helpful in the management of cardiovascular diseases.
