Abstract
Objective : This study was conducted to investigate the antioxidant activity and inhibitory effect on oxidative DNA damage of Nelumbinis Semen Extracts Methods : Nelumbins semen were extracted with hot-water and ethylacetate (EtOAC). The 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl radical scavenging assay and $Fe^{2+}$ chelating assay were performed for antioxidative effect and ${\phi}X$-174 RF I DNA cleavage assay and intracellular DNA damage assay were used for inhibitory effect on intracellular DNA damage. Results : In DPPH, Hydroxyl radical scavenging activity and $Fe^{2+}$ chelating activity of EtOAC extracts were 96.22%, 53.53%, 64.72%, while those of hot-water extracts were 20.86%, 10.72%, 29.74% at $200{\mu}g/m{\ell}$, respectively. In ${\phi}X$-174 RF I plasmid DNA cleavage assay, the protective effects of EtOAC and hot-water extracts against oxidative DNA damage were 76% and 6% at $200{\mu}g/m{\ell}$, respectively. Conclusion : These results indicated that the seed extracts of Nelumbo nucifera can be used as a natural antioxidants, which effectively inhibits the oxidative DNA damage.
