| Abstract: | Antioxidant activities,including reducing capacity,DPPH free radial scavenging,superoxide anion scavenging,hydroxyl free radical scavenging and anti-lipid peroxidation,of the alcohol extract from Galla Chinensis were studied and compared with VC or VE.The results showed that the antioxidant activities were increased with the concentration of alcohol extract.When studied at the same concentration,both the reducing capacity and superoxide anion scavenging capacity of the extract from Galla Chinensis were higher than that of VC,its DPPH and hydroxyl radical scavenging capacity were lower than VC,and its anti-lipid peroxidation was lower than VE. |
