This study was conducted to investigated the antioxidant activities of extract for Megmoondong fruit. Liriope platyphylla L. was extracted with 70% methanol at room temperature for 48 hr and concentrated under reduced pressure to measure its total polyphenol contents and electron donating ability. The total polyphenol contents were 7,253.50±335.43 μg GAE/mL in 70% methanol extract, 1,239.77±9.30 μg GAE/mL in methylene chloride fraction, 919.30±50.83 μg GAE/mL in methanol fraction, 105.44±2.04 μg GAE/mL in ethyl acetate fraction. The total polyphenol contents showed significant differences (p<0.05) between the solvents. The electron donating ability was 69.17±12.61% for 70% methanol extract, 33.11±1.77% for methylene chloride fraction, 5.19±2.59% for ethyl acetate fraction, and 20.16±1.04% for methanol fraction. The electron donating abilities were significantly different (p<0.05) between the solvents. The removal ability of superoxide radical was 0.0174±0.0007 for 70% methanol extract, 0.0164±0.0007 for methylene chloride fraction, 0.0172±0.0007 for ethyl acetate fraction, and nothing for methanol fraction. The measurement of hydrogen peroxide decomposition was 0.0985±0.1021 for 70% methanol extract, 0.0896±0.0893 for methylene chloride fraction, 0.0115±0.0085 for ethyl acetate fraction, and 0.0170±0.0180 for methanol fraction. The Liriope platyphylla L. extracts obtained from methylene chloride showed significantly relevant results in the total polyphenol contents and electron donating ability, which was higher than the original extract.
