Abstract :Aronia is among the most antioxidant containing plants which is found commonly around the world. Aronia cultivation started in Turkey for the first time in 2012 at the Atatürk Central Research Institute of Garden Cultures, and a plantation was constructed in the experimental area. Since antioxidants help to preserve food by blocking oxidation processes and contributing to the health promotion provided by numerous dietary supplements, nutraceutical and functional food additives, antioxidant capacity of these plants should be well characterized. To assess and evaluate the antioxidant content of foods and plant products, many approaches are utilized. In this study, catalase insert ignore into journalissuearticles values(CAT); enzyme was partially purified from aronia plant leaf tissue and characterization was carried out. Purification process consisted of homogenate preparation, ammonium sulfate precipitation and dialysis. The optimal ionic strength, pH, substrate concentration and enzyme quantity were examined. These values were found to be 300 mM Tris, pH:8.0, 12 mM H 2 O 2 and 75 μl, respectively, for the catalase enzyme of the Aronia plant leaf tissue. This study is the first in the literature dealing with the characterization of antioxidant enzyme from Aronia plant.
