초록
The present study attempts to evaluate antioxidant activities of extracts from Abeliophyllum distichum. Nakai flower. The samples were collected in Jangyyeon-myeon, Goesan-gun, Korea and extracted with either hot-water or ethyl acetate (EtOAC). In DPPH, hydroxyl radical scavenging activity and Fe2+ chelating activity of EtOAC extracts were 93.41%, 98.43%, and 7.38%, while those of hot-water extracts were 86.93%, 41.33% and 47.68% at 200 μg/ml,respectively. In φX-174 RF I plasmid DNA cleavage assay, the protective effects of EtOAC and hot-water extracts against oxidative DNA damage were 82% and 17% at 200 μg/ml, respectively. Both extracts showed the protective effect of DNA migration by oxidative stress in intracellular DNA migration assay. Both extracts had no cytotoxity in NIH3T3 cells. Several polyphenolic compounds were identified such as 2-methoxy-benzoic acid, vanillic acid, phytol and pulegone by GC/MS. These results indicated that extracts of Abeliophyllum distichum Nakai flower showed antioxidant activities and protective activities against oxidative DNA damage and showed the possibility to be used as an effective natural antioxidants.
