Abstract
Antioxidative activities of ethanol extracts of fruits from three cultivars of Prunus mune with different harvest times were determined. Extracts of P. mune cutivar Okyoung showed the strongest activity at 97.5%(compared to BHT) using DPPH or thiocyanate method, although no statistically significant differences were observed among the cultivars. Antioxidative activities of the extracts measured with glutathione-S-transferase method was over 70% of that of BHT. Survival rates of cells in mouse spinal cord culture challenged by superoxide anion were 89, 79, and 62% at 40 mg/ml of Okyoung, Namgo, and Kochunme extracts, respectively, whereas 90% at 6mM glutathion.
