中文摘要: 该文对19 种食用菌水提物与醇提物活性成分含量及抗氧化活性进行检测与比较。结果表明,不同食用菌提取物活性成分含量及抗氧化能力具有明显差异。其中猪肚菇水提物中多糖含量最高,为4 331.65 μg/mL;蛹虫草水提物中总多酚和总黄酮含量最高,分别为556.88 μg/mL 和68.38 μg/mL。抗氧化活性方面,灵芝醇提物DPPH·清除能力、蛹虫草水提物ABTS+·清除能力、姬松茸醇提物羟自由基清除能力较强,分别为92.36%、90.07%、92.31%。同种食用菌的水提物与醇提物活性成分含量及抗氧化能力也存在明显差异。以吸光度大小衡量总还原力强弱,竹荪醇提物总还原力达到1.35,而其水提物为0.62。相关性分析结果表明,总多酚和总黄酮含量与抗氧化活性相关性较强,与DPPH·清除能力、ABTS+·清除能力和总还原力呈极显著正相关。
Abstract:The content of active components and antioxidant activity of water and alcohol extracts from nineteen edible mushrooms were evaluated and compared. The results showed that there were significant differences in active component content and antioxidant activity among different edible mushroom extracts. Among the surveyed mushrooms,the highest polysaccharide content was observed in the water extract of Clitocybe maxima,which was 4 331.65 μg/mL. The highest content of total polyphenols and total flavonoids was found in the water extract of Cordyceps militaris,which was 556.88 μg/mL and 68.38 μg/mL,respectively. For antioxidant activity,the alcohol extract of Ganoderma lingzhi (with 92.36% DPPH· scavenging ability),the water extract of C. militaris (with 90.07% ABTS+· scavenging ability),and the alcohol extract of Agaricus blazei (with 92.31% hydroxyl radical scavenging ability) demonstrated good performances. In addition,there were also significant differences in active component content and antioxidant activity between water and alcohol extracts of the same edible mushroom. As measured by absorbance,the total reducing power of Dictyophora indusiata alcohol extract reached 1.35,while that of its water extract was 0.62. The results of correlation analysis showed that the content of total polyphenols and total flavonoids has strong correlation with antioxidant activity,exhibiting highly significant positive correlation with DPPH· scavenging capacity,ABTS+· scavenging capacity,and total reducing power.
