Ethnopharmacological relevance: The Sida cordifolia L (Family: Malvaceae) is a widely allocated herb by folk tribes of Gujarat state of India for the treatment of coronary manifestations. However, no published data relevant to use of the plant is available. Aim of the study: The aim of the present study was to evaluate the antioxidant and biochemical profile of hydroalcoholic extract of Sida cordifolia L (HESC) leaves against myocardial infarction (MI) in rats. Materials and methods: Albino rats were administered HESC (100 and 500 mg/kg) and propranolol (10 mg/kg) once daily orally for 30 days. At the end of treatment period, MI was induced by administering isoproterenol (ISO) or by subjecting heart to ischemia reperfusion injury (IRI). Endogenous biomarkers (LDH and CK-MB) and antioxidants (SOD and catalase) were estimated in serum/perfusate and heart tissue homogenate (HTH). Results: The LDH and CK-MB activities were elevated in HTH and depleted in serum/perfusate of HESC and propranolol groups when compared to ISO/IRI control. Further, it was found that both doses significantly increased endogenous antioxidants in HTH. Moreover, biochemical findings were supported by histopathological observations. Conclusion: The result confirm, at least in part, for the use of Sida cordifolia in folk medicine to treat MI. (C) 2009 Elsevier Ireland Ltd. All rights reserved.
