摘  要:研究了黄蒿Artemisia scoparia挥发油对几种植物受体的化感作用,分析了挥发油的化学成分。结果表明:黄蒿挥发油对萝卜Raphanus sativus、苜蓿Medicago sativa、白菜Brassia pekinensis、玉米Zea mays种子萌发和幼芽、幼根伸长生长具有不同程度的抑制作用。对萝卜种子抑制作用最强,最终萌发率比对照减少27.3%。对苜蓿的幼芽和幼根的抑制作用最显著,分别比对照减少19.2%和33.4%。用GC-MS-DS联用方法,共鉴定出挥发油中的38种化合物,检出物占总质量的87.53%,其中萜烯类12种,占45.04%。相对百分含量在1.5%以上的化合物有10种:1)2,5-亚乙烯基[4,2,2]螺桨-3,7,9-三烯;2)斯巴醇;3)石竹烯;4)1,2-二甲氧基-4(2-丙烯基)苯;5)石竹烯氧化物;6)毛蒿素;7)橙花叔醇;8)β-法呢烯;9)1-(1,5-二甲基-4-己基)-4-甲基苯;10)大根香叶烯。This paper studied the allelopathy effects and chemical compositions of Artemisia scoparia volatile oil. The results showed that volatile oil has different inhibition effects on seeds germination and seedling growth of radish, Lucerne, Chinese cabbage and maize. In comparison with control, seed germination of radish decreased by 27.3%, while root and seedling of Lucerne growth were reduced by 19.2% and 33.4%, respectively. Chemical analysis of the volatile oil was performed by means of GC-MS-DS. 38 chemical components was identified. The content of the identified compounds made up 87.53% of the total substances detected, including 12 terpenoids compounds, 45.04% of the total substances detected. The relative contents of chemical components more than 1.5;were identified as : 1) 2,5-Etheno[-4,2,2] propella-3,7,9-triene; 2) Spathulenol ; 3) Caryophyllene; 4) Benzene, 1,2-di- methoxy-4-(2-propenyl) ; 5) Caryophyllene oxide; 6) Capillin; 7) Trans Nerolidol; 8) Beta-Farnesene; 9) Benzene, 1-(1,5-dimethyl-4-hexenyl)-4-methyl ; 10) Germacrene.
