| 摘 要： | 目的]芸香草不同极性提取物中多酚含量的测定并研究其体外抗氧化活性。方法]用70%乙醇、氯仿、乙酸乙酯、正丁醇和水等溶剂对云香草进行提取,分别测量其中的多酚含量,并以其中的多酚为基准,比较分析各提取物的抗氧化活性。结果]云香草70%乙醇、氯仿、乙酸乙酯、正丁醇和水提取物多酚含量分别为3.87、0.52、0.41、0.83和1.57 mg/g,即提取液极性增大时,多酚含量也相应增加;各提取物均有一定的抗氧化活性,所含多酚质量浓度相同时,70%乙醇和水提取物的抗氧化活性较大,并与抗坏血酸相近,而氯仿、乙酸乙酯、正丁醇的抗氧化活性较小。结论]芸香草多酚以极性多酚为主,且其抗氧化活性随多酚极性的增加而加强的趋势。

| Abstract: | Objective] To determine polyphenolics from different polarity extracts of Cymbopogon distans and research antioxidant activity. Methods] The ethanol extract of Cymbopogon distans was extracted by different polar solvent in turn, its polyphenolics were determined, and the antioxidant activity were measured. ~ Result] All extracts from Cymbopogon distans had some antioxidant activities, 70% alcohol extract and water extract showed the highest antioxidant activity as Vc under the same content of polyphenols conditions but the antioxidant activity of chloro-form extract, ethyl acetate extract and n-butanol extract are smaller in comparison Vc. Conclusion] Polar polyphenols were dominant in Cymbo-pogon distans, with the improvement of the extraction solvent polarity, its antioxidant activities showed an increasing trend. |
