摘　　要：探讨蒙古栎木醋液及酸类成分的抗氧化活性,研究蒙古栎木醋液对小麦(Triticum aestivum)种子萌发的影响。蒙古栎木醋液及乙酸和山梨酸抗氧化实验结果表明蒙古栎木醋液抗氧化活性是多种成分共同作用结果,蒙古栎木醋液抗氧化活性均高于质量浓度28.36%乙酸和质量浓度6%山梨酸,蒙古栎木醋液对DPPH自由基清除率效果较好,半数抑制浓度IC_(50)为(40.15±0.07)g/L。蒙古栎木醋液对小麦种子萌发呈现浓度低促高抑的效果,蒙古栎木醋液对小麦种子萌发实验结果表明稀释2000倍时,与对照相比差异显著(P<0.05),发芽率增加18%。Explore the antioxidant activity of mongolian oak wood vinegar and its acid components,and study the effect of mongolian oak wood vinegar on wheat(Triticum aestivum)seed germination.The results of antioxidant experiments on mongolian oak wood vinegar with acetic acid and sorbic acid showed that the antioxidant activity of mongolian oak wood vinegar was the result of a combination of multiple components.The antioxidant activity of mongolian oak wood vinegar was higher than the mass concentration of 28.36%acetic acid and 6%sorbic acid.Mongolian oak wood vinegar had a good effect on DPPH radical scavenging rate,with a half inhibitory concentration of IC_(50) of(40.15±0.07)g/L.Mongolian oak wood vinegar has a low concentration promoting and high inhibiting effect on wheat seed germination.The experimental results of mongolian oak wood vinegar on wheat seed germination showed that when diluted 2000 times,there was a significant difference compared to the control(P<0.05),and the germination rate increased by 18%.
