Objective: To study the antioxidant activities of five extracts of Amomi longiligulare (A. longiligulare) to determine the antioxidant fraction. Methods: The ethanol extract of A. longiligulare was extracted by systematic solvent extraction to obtain the petroleum ether, dichloromethane, ethyl acetate, n-butanol fractions successively. The in vitro antioxidant activities of the five extracts were evaluated by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical and hydroxyl radical (OH-) scavenging assay methods. Results: The five extracts showed different extent of antioxidant activities in vitro, especially the ethyl acetate and dichloromethane fractions. Conclusion: The difference of antioxidant activity of different extracts may be associated with the type and structure of antioxidant components in each fraction of A. longiligulare fruits. |
