摘 要: 对我国3种主要红景天品种植物的总黄酮物质进行提取,分别对其1,1-二苯基-2-三硝基苯肼(DPPH),•OH-,O2-•,以及亚硝酸盐的清除能力和Fe2+螯合能力及总抗氧化能力进行评价,从而比较分析其抗氧化活性。结果表明,大花红景天(Rhodiola crenulata)中总黄酮类物质含量较柴胡红景天(R. bupleuroides)和长白红景天(R. angusta)多,且其Fe2+螯合能力、O2-•清除能力、总抗氧化能力均高于其余两者;柴胡红景天中总黄酮类物质对DPPH,•OH-,亚硝酸盐的清除能力均高于大花红景天和长白红景天。

Abstract: The total flavonoids from 3 major species of Rhodiola rosea in China were extracted. The scavenging rates of DPPH, •OH- , O2-•, NO2 free radicals, chelating of Fe2+, and total antioxidant capacity were adopted to evaluate the total flavonoids of three Rhodiola plants in vitro. The results show that the content of flovonoids in R. crenulata was higher than R. bupleuroides and R. angusta, and the scavenging effect of Fe2+ chelating, O2-• scavenging, and total antioxidant capacity of R. crenulata were also higher than the others. The scavenging effects of DPPH, •OH- and nitrite of R. bupleuroides were the strongest.
Key words: science of Chinese medicinal material resources; Rhodiola rosea; total flavonoids; antioxidant; free radical
