摘要: 利用气相色谱-质谱法对水蒸气蒸馏提取小蓬草精油的挥发性组分进行了分析,匹配度83%以上的活性组分有5种,其中4种为萜类化合物(柠檬烯、α-佛手柑油烯、顺式-β-金合欢烯、反式-β-金合欢烯)。通过纸上种子发芽的生物测定试验,结果表明,小蓬草精油对受体植物青菜、白菜、小麦、高粱种子萌发具有抑制作用,小蓬草精油对4种受体植物种子萌发具有50%抑制作用的丙酮溶液的适宜浓度IC50分别为0.4、0.6、0.4、0.8 g/L。精油的活性组分主要有柠檬烯等萜类化合物、2,3-二甲基-4(3H)-喹唑啉酮等酮类化合物。

Abstract: The volatile components of Conyza canadensis essential oil from steam distillation were analyzed by gas chromatography-mass spectrometry (GC-MS). There are five kinds of active components with match of more than 83%, of which four components are terpenoids (limonene, α-bergamotene, (E)-β-farnesene, (Z)-β-farnesene). The results of standard seed ger mination assay on paper showed that the essential oil of C.canadensis had inhibition effects on seed ger mination of the receptor plants (Brassica chinensis Linn., B.pekinensis Rupr., Triticum sestivum Linn., Sorghum bicolor(Linn.)Moench). The essential oil of C.canadensis on the receptor plants seed ger mination to 50% inhibition of the appropriate concentration of acetone IC50 were 0.4, 0.6, 0.4, 0.8 g/L, respectively. The active components of essential oil from C.canadensis are mainly terpenoids (limonene, etc.) and ketones (2,3-dimethyl-4(3H)-quinazolinone,etc.).
