摘　　要：[目的]探寻紫甘薯花青素苷的抗氧化活性。[方法]采用微波加热-酸化水提取新技术,从紫甘薯中提取花青素苷酸化水粗提物,然后给12月龄小鼠(老龄小鼠)灌胃不同浓度(100、500和1000mg/kg)的酸化水粗提物30d,测定血清中抗氧化指标。[结果]12月龄小鼠被浓度为1000mg/kg花青素苷酸化水粗提物灌胃30d后,其体内抗衰老指标与对照组5月龄小鼠相当。[结论]紫甘薯色素提取物具有明显的抗生物氧化作用,可延缓衰老。[Objective] To explore the antioxidant activity of anthocyanin in purple sweet potato. [Method] The anthocyanin extracts from purple sweet potato were prepared by means of microwave heating -acidified water extraction technology. After the aged mice were given anthocyanin extracts at the concentrations of 100,500 and 1 000 mg/kg by gavage for 30 d,the anti-oxidations in serum were determined. [Result] After given anthocyanin extracts at concentration of 1 000 mg/kg by gavage for 30 d,the anti-aging indicators of aged mice （at 12 months old） agreed with that of 5-month-old mice in vivo in control group. [Conclusion] The anthocyanin extracts from purple sweet potato has obvious anti-oxidation and can delay aging.
