为稠李果实的进一步开发利用提供基础依据，采用亚油酸体系-硫氰酸铁测定原花青素抗氧化力等方法，研究稠李果实原花青素对 DPPH·、O2-·和·OH 3种自由基的清除效果，并与抗坏血酸的抗氧化力进行比较。结果表明：0．15 mg/mL 的稠李果实原花青素和抗坏血酸均能不同程度抑制亚油酸自氧化，抑制率分别为46．9％和16．9％；稠李果实原花青素对 DPPH·、·OH 和 O2-·的最大清除率分别为97．8％、32．0％和96．5％，抗坏血酸对 DPPH·、· OH 和 O2-·的最大清除率分别为43．0％、27．4％和75．5％。稠李果实原花青素和抗坏血酸对自由基的清除率均随浓度增加而呈上升趋势，稠李果实原花青素的抗氧化性明显强于抗坏血酸。

The scavenging effect of procyanidine in Padus racemosa fruits on DPPH ·,O2- · and ·OH free radicals was studied by the linoleic acid-thiocyanatoiron method,and the antioxidant resistance was compared with ascorbic acid to provide the scientific basis for further development and utilization of Padus Racemosa fruits. The results showed that 0.15 mg/mL procyanidine extracted from Padus racemosa fruits and ascorbic acid both can inhibit auto-oxidation of linoleic acid to varying degrees,and the inhibition rate of procyanidine and ascorbic acid is 46.9% and 16.9% respectively.The maximum scavenging rate of procyanidine extracted from Padus racemosa fruits to DPPH ·,·OH and O2- is 97.8%,32.0% and 96.5% separately,and the maximum scavenging rate of ascorbic acid to DPPH·, ·OH and O2- · is 43.0%,27.4% and 75.5% respectively.The scavenging rate of procyanidine extracted from Padus racemosa fruits and ascorbic acid to free radicals shows a rising trend with increase of concentration,and the inoxidizability of procyanidine extracted from Padus racemosa fruits is higher than ascorbic acid significantly.
