Chrysanthemum morifolium (C. morifolium) is a perennial plant herb widely distributed in Korea and has been used in a traditional herbal remedy for various diseases. This study was conducted to determine antioxidant activities and antigenotoxic effect in water, acetone, ethanol and methanol extracts from white and yellow C. morifolium flowers (WC and YC). The antioxidants properties were evaluated on the basis of total phenolic content (TPC), DPPH radical-scavenging activity (RSA) and superoxide dismutase (SOD)-like activity. The highest TPC (5.09 g/100 g GAE) showed in YC methanol extract. The DPPH RSA activity of WC and YC water extracts increased as its concentration increase from 50 to 1000 mg/mL, respectively, and the lowest IC50 of DPPH RAS showed in YC of 25°C. Also, WC solvent extracts showed significantly higher DPPH RSA than YC solvent extracts. The SOD-like activity of YC water extracts were higher than WC water extracts. And, YC acetone extract and WC methanol extract showed significantly higher SOD-like activity than WC acetone extract and YC methanol extract, respectively. The antigenotoxicity of WC and YC extracts were determined by measuring inhibitory effects of H2O2 induced DNA damage in human leukocytes using the comet assay, resulting that the ethanol extracts of WC and YC showed a significant antigenotoxic effect against oxidative stress. These results suggest that C. morifolium has significant antioxidant activity and protective effect against oxidative DNA damage.
