Antioxidative Activity of Anthocyanins from Northland

摘要： [Objective] To explore antioxidative activity of anthocyanins from Northland. [Method] Using anthocyanins from grape seeds and vitamin C as positive control, Fenton reacting system, pyrogallol autoxidation system, linoleic acid system and Prussian blue method were respectively employed to determine OH·scavenging activity,O-2·scavenging activity, inhibitive effect on lipid peroxidation and reducing capacity of anthocyanins from Northland. [Result] Antioxidative activity of anthocyanins from Northland was higher than that in anthocyanins from grape seeds and vitamin C. Anthocyanins from Northland had strong scavenging activities on OH·and O-2·,IC50 of which was 0.345 mg/ml and 34.28 μg/ml, respectively. Furthermore, it was also provided with obvious inhibiting activity on lipid peroxidation and reducing capacity. [Conclusion] Anthocyanins from Northland may be a potential natural medicine with antioxidative activity. ... （共3頁(yè)）
