Preliminary study on antioxidant activity of Chinese liquor

In this study, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) , total antioxidant activity, reducing capacity, and chelating capacitywere used to evaluate the antioxidant activity of Chinese liquor. According to each method under study, Chinese liquors had lower antioxidant activity than synthetic antioxidants. The scavenging activity of Chinese liquor was 7.80% ±2.31%. The inhibiting percentage was 20.50% ±8.08%. The chelating activity was 1.60%±0.84%. The reducing capacity was 0.18±0.06 expressed by absorbance.
