Radical Scavenging Activity of the Extraction with 50% Ethanol from Epicarp of WenYeIICoconut
The radical scavenging activity of natural pigments extracted from the epicarp of Wen Ye Ⅱcoconut was studied,including the reducing power,DPPH radical scavenging activity,hydroxyl radical scavenging activity and so on.And vitamin C,vitamin E,gallic acid and BHT were used as the control.The results showed that the scavenging activity of DPPH radical and hydroxyl radical was very well,and the reducing power was also good.And the lipid oxidation scavenging activity was higher than vitamin C,however the metal chelating activity of the pigments of the epicarp of WenYe Ⅱcoconut was lower the control.It meant that the pigments from the epicarp of WenYe Ⅱcoconut had a better radical scavenging activity and good health care function.
