Using Shaoxing rice wine as control,the scavenging activity of the Hakka rice wine on DPPH ·,O2·-,ABTS·,·OH was determined.The results showed that different brands of Hakka rice wine had flavones,polyphenol,phenolic acids.The alcohol content,soluble solids,total flavones content,polyphenol content,total phenolic acids content of Hakka rice wine were as follows respectively:Zhenzhuhongniang 16.3 1％vol,103.42 g/L,0.89 mg/L,11.98 mg/L,0.19 mg/L;Meizhouniang 15.63％vol,101.72 g/L,1.86 mg/L,10.3 mg/L,0.42 mg/L;Yuezi 13.42％vol,91.90 g/L,1.61 mg/L,12.13 mg/L,0.56 mg/L.The three Hakka rice wine all showed scavenging activity on DPPH·,O2·-,ABTS·,and ·OH,and the IC50 values towards the four free radicals were as follows respectively:Zhenzhuhongniang 68.05 μl/ml,388.11 μl/ml,405.71 μl/ml,438.54 μl/ml;Meizhouniang 55.94 μl/ml,378.09 μl/ml,387.90 μl/ml,440.80 μl/ml;Yuezijiu 98.63 μl/ml,871.65 μl/ml,345.42 μl/ml,935.20 μμl/ml.In comprehensive consideration,the antioxidant activity of Zhenzhuhongniang and Meizhouniang rice wine were higher than Yuezi and Shaoxing rice wine.
