Abstract: The present study was carried out to determine and compare the abilities of the ethanol extract and its different polarity fractions (obtained by extracting the ethanol extract with different polarity solvents) from the bulb of Lilium lancifolium Thunb. to scavenge DPPH· and ABTS+·, reduce ferric ion and inhibit lipid peroxidation in vitro. The ethanol extract and its ethyl acetate fraction and n-buthanol fraction revealed strong scavenging effect on DPPH· and ABTS+·, reducing effect on Fe3+, and inhibitory activity on lipid peroxidation. These results may be helpful for further developing the bulb of Lilium lancifolium Thunb. as a healthcare food.

Key words: Lilium lancifolium Thunb., antioxidant activity, free radical scavenging activity, bioactive fractions
