摘要
研究两种真姬菇不同溶剂提取物的抗氧化活性和多酚含量。制备真姬菇粗提物、正己烷萃取物、乙酸乙酯萃取物、正丁醇萃取物与水萃取物,分析它们的抗氧化活性与测定它们的多酚含量。结果表明:闽真2号正己烷萃取物的总抗氧化能力最好,乙酸乙酯萃取物清除DPPH自由基能力最强,正丁醇萃取物清除ABTS自由基能力最强;闽真3号乙酸乙酯萃取物的总抗氧化能力、清除DPPH与ABTS自由基能力均最好。相关性分析结果表明,真姬菇多酚含量与DPPH自由基清除能力具有一定的相关性。综合考虑抗氧化活性与萃取率,正己烷萃取物与乙酸乙酯萃取物可被作为天然抗氧化剂应用于食品科学领域。
The antioxidant properties and total polyphenol contents of various solvent extracts from two Hypsizygus marmoreus strains were investigated. Crude extract, hexane fraction, ethyl acetate fraction, butanol fraction and aqueous fraction of Hypsizygus marmoreus were prepared. Their antioxidant properties were studied and their total polyphenol contents were determined.Results obtained in this study showed that, as for MinZhen No. 2, the highest total antioxidant activities, DPPH radical scavenging activities and ABTS radical scavenging activities were found for hexane fraction, ethyl acetate fraction and butanol fraction,respectively.As to MinZhen No.3, the highest total antioxidant activities, DPPPI radical scavenging activities and ABTS radical scavenging activities were exhibited by ethyl acetate fraction. Correlation analysis results showed that total polyphenol contents had a relation with DPPH radical scavenging activities. Hexane fraction and ethyl acetate fraction of Hypsizygus marmoreus could be used as a source of natural antioxidant applied in food science when taking into account the combination of antioxidant properties and extraction yields.
