摘　　要：以蒙古栎叶与木醋液为原料,采用气相色谱-质谱(GC-MS)分别分析其成分,结果表明,蒙古栎叶提取物相对含量较高的成分,2,3-二甲基-2-环戊烯-1-酮(13.49%)、2-甲基苯酚(9.22%)等。木醋液相对含量较高的成分,愈创木酚(28.27%)、苯酚(7.78%)、对甲酚(4.97%)、2,3-二甲基-2-环戊烯-1-酮(4.93%)等。种子萌发实验表明,相比对照组,叶提取物稀释50、100、200、400倍对小白菜发芽率抑制显著,稀释50、100、200、400、800、1600倍对芥菜发芽率抑制显著;木醋液稀释50倍对芥菜发芽率抑制显著,叶提取物与木醋液中所含酚类物对种子发芽率有一定抑制作用。Using mongolian oak leaves and wood vinegar as raw materials,the components were analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the components with higher relative content in mongolian oak leaf extract were 2,3-dimethyl-2-cyclopentene-1-one(13.49%),2-methyl phenol(9.22%),etc.The components with higher relative content in wood vinegar include guaiacol(28.27%),phenol(7.78%),p-cresol(4.97%),2,3-dimethyl-2-cyclopentene-1-one(4.93%),etc.The seed germination experiment showed that compared with the control group,leaf extract diluted 50,100,200,and 400 times significantly inhibited the germination rate of pakchoi,while diluted 50,100,200,400,800,and 1600 times significantly inhibited the germination rate of mustard;Diluting wood vinegar 50 times significantly inhibits the germination rate of mustard,while phenolic compounds in leaf extracts and wood vinegar have a certain inhibitory effect on seed germination rate.
