    Objective: In this study, Rosa pisiformis was evaluated for its antioxidant activity, vitamin (A, E, C), trace element (Fe, Cu, Zn, Mn, Cr, Se) and mineral (Ca, K, Mg, Na) levels, in addition to its cardioprotective effects on cardiac tissue antioxidant enzymes (GSH-Px, SOD, CAT) during isoproterenol (ISO) - induced oxidative stress. Methods: In the study, vitamin and mineral analysis was carried out using HPLC and ICP-MS method, R. P. antioxidant and antiradical properties were determined using spectrophotometer. Forty wistar albino rats were divided into four groups: control (0.9% NaCl), ISO (100 mg/kg), ISO (100 mg/kg) + R. P. (300 mg/kg) and R. P. (300 mg/ kg). ISO was injected subcutaneously into rats twice at an interval of 24 h for two consecutive days (on 28th and 29th day). R. P. fruit administered daily. The experimental period was continued for 30 days. Results: The results of the study indicated that R. P. fruit and leaves contain high levels of minerals and vitamins and possess antioxidant and antiradical activity and its fruits have positive effects on cardiac tissues. The results are supported with significant changes in antioxidant enzyme levels and histopathological examination. Conclusion: This study demonstrates that R. P. fruits in particular can be used to treat and prevent cardiac diseases. © 2016, Turkish Biochemistry Society. All rights reserved.
