Abstract
|
|
|
Objectives : This research aimed to evaluate the effects of Rubus coreanus .
Methods: These extracts from fresh R. coreanus . 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 . possesses remarkable radical scavenging activity. The content of total phenolics of the ethanol extract from dried R. coreanus . (=155.878.8g/mL) is the highest among all of the samples. The stronger radical-scavenging activity (=77.722.1g/mL) of ethyl acetate extract from dried R. coreanus . should be related to its phenolic content as measured by gallic acid test.
Conclusion: These results suggest that dried R. coreanus . may act as a potential antioxidant agent.
