Objectives: This research aimed to evaluate the effects of Rubus coreanus MIQ. Methods: These extracts from fresh R. coreanus MIQ. were investigated with radical scavenging activity, the content of total phenolics, ferric thiocyanate method and flavonoid contents Results: These results revealed that the ethyl acetate extract from fresh R. coreanus MIQ. possesses remarkable radical scavenging activity. The content of total phenolics of the ethanol extract from dried R. coreanus MIQ. (IC50=155.87±8.8μg/mL) is the highest among all of the samples. The stronger radical-scavenging activity (IC50=77.72±2.1μg/mL) of ethyl acetate extract from dried R. coreanus MIQ. should be related to its phenolic content as measured by gallic acid test. Conclusion: These results suggest that dried R. coreanus MIQ. may act as a potential antioxidant agent.
