鼠尾草提取物多酚含量与抗氧化活性的研究

The polyphenolic contents and antioxidant activities of Salvia officinalis extracts

  • 摘要: 研究从不同的角度来评价鼠尾草提取物的抗氧化活性。采用50%丙酮和70%乙醇两种溶剂对鼠尾草进行提取,用Folin-Ciocalteu法测定提取物中的多酚含量,并用四种方法,即清除DPPH(1,1-二苯基-2-三硝基苯肼)自由基法、螯合Fe2+法、还原力法和磷钼络合物法测定提取物的抗氧化活性。研究结果表明,50%丙酮提取物中的多酚含量显著高于70%乙醇提取物。鼠尾草提取物具有良好的自由基清除能力、螯合Fe2+能力、还原能力和总抗氧化能力。鼠尾草50%丙酮提取物的抗氧化活性总体上比70%乙醇提取物高(还原力除外)。 

     

    Abstract: The antioxidant activities of Salvia officinalis (sage) extracts from various perspectives were evaluated.Sage powder were extracted with 50% acetone and 70% ethanol, the polyphenol content and antioxidant activity of sage extracts were determined by Folin-Ciocalteu method and DPPH radical scavenge, chelating Fe2+, reducing power, phosphomolybdenum methods, respectively.The result indicated that the polyphenol content of extract in 50% acetone was significantly higher than extract in 70% ethanol.Both of the sage extracts possessed proper free radical scavenging activity, metal ions chelating activity, reduction activity and total antioxidant ability.In general, except for reducing power, the antioxidant activity of sage extract in 50% acetone was higher than in 70% ethanol.
