        The aim of this research was to investigate the anti-oxidantive activities of extracts from Chionanthus retusus leaves, fruits and flower. The content of phenolics were 20.8 mg/g in water extracts and 32.2 mg/g in 90% ethanol extracts from flower. The DPPH free radical scavenging activity of extracts from Chionanthus retusus was above 70% at phenolic concentration 100 μg/mL. The ABTS radical decolorization activities of water and ethanol extracts were both above 80% at 100 μg/mL phenolic concentration, respectively. The antioxidant protection factor(PF) of water and 80% ethanol extracts from leaves was the highest as 2.27 PF and 1.70 PF at 50 μg/mL phenolic concentration. The TBARs inhibition rate of the Chionanthus retusus extracts, was above 70% at 200 μg/mL phenolic concentration. The anti-oxidantive activities of extracts from leaves were shown more active than BHT as a positive control except TBARs. These results confirmed that the extracts from Chionanthus retusus leaves, fruits and flower was shown the high anti-oxidant activity. The results can be expected isolated phenolic compounds from Chionanthus retusus to use as functional beauty food resource.
