The aim of this research is to determine H 2 O 2 radical scavenging and total antioxidant activity of Crataegus monogyna (hawthorn) water and ethanol extracts of leaves, flowers and fruits. Hawthorn leaves, flowers, and berries are used in traditional medicine in the treatment of chronic heart failure, high blood pressure, arrhythmia, and various digestive ailments, as well as geriatric and antiarteriosclerosis remedies. In this study, ethanol and water extracts were prepared from powdered C. monogyna flowers, leaves and fruits. Antioxidant activities were measured by ferric thiocyanate method, H 2 O 2 radical scavenging assays with UV-Vis spectrophotometer. In conclusion, C. monogyna flowers, leaves and fruits had H 2 O 2 radical scavenging, total antioxidant activity, and these antioxidant activities were compared with BHA and α-tocopherol as reference antioxidants. The results of this study show that the water and ethanol extracts of C. monogyna can be used as easily accessible source of natural antioxidants and as a possible food supplement or in pharmaceutical industry.
