Antioxidant Effect of Water Extract from Soybean

Changhong Jia

Abstract

The antioxidant effect of water extract from Soybean was studied by the methods of pyrogallic autoxidation,salylic acid and DPPH· to assay superoxide,hydroxyl free radical and DPPH· free radical.The result showed that the extract of Soybean had capacities of scavenging superoxide,hydroxyl free radical and DPPH· free radical compared with the VitaminC as positive control,and the IC50 values were 121.60μg /mL,28.4μg /mL,32.8μg /mL respectively.It indicated that the water extract may be used as antioxidant additive in foods and cosmetics.
