摘要: 为了研究6种伞形科植物挥发油的杀螨效果,分析活性最好的植物挥发油的主要活性成分。采用水蒸气蒸馏法提取香菜、白芷、柴胡、大齿山芹、辽蒿本、川芎6种伞形科植物挥发油。以玻片浸渍法测定其挥发油杀螨活性后,使用气质联用仪(GC-MS)对具有较好杀螨活性的挥发油化学成分进行分析。结果表明香菜、白芷、柴胡、大齿山芹、辽蒿本、川芎挥发油杀螨的半数致死浓度(LC50)分别为2.9006、1.1575、3.2386、1.6314、1.8854、0.3767 mg/mL,其中以川芎挥发油的杀螨活性最强,其主要成分为4-萜烯醇(11.81%)、双环(2,2,1)庚烷-2-醇1,7,7-三甲基-2-乙酸酯(8.28%)、4-乙烯基-2-甲氧基苯酚(14.88%)、苯戊酮(7.92%)、苯己醇(9.87%)。本研究首次发现川芎挥发油对朱砂叶螨具有较好的触杀作用。毒杀效果与市售常用杀螨剂螺螨酯(LC50=356.8878 mg/L)相对持平。因此推测4-萜烯醇可能是杀螨的活性成分之一。

Abstract: The aim was to study the acricidal activity of six essential oil from Umbelliferae plants against Tetranychus cinabarinus B.. Six essential oils were extracted by steam distillation method from Coriandrum sativum L., Angelicae Dahuricae, Bupleurum chinense, Angelica grosseserratum, Ligusticum jeholense, Ligustici Chuanxiong, respectively. Their acricidal activities were checked by slide-dip method; and chemical constitution were analyzed by gas chromatography mass spectrometry (GC-MS) method. The results show that their half lethal concentration (LC50) were 2.9006 mg/mL, 1.1575 mg/mL, 3.2386 mg/mL, 1.6314 mg/mL, 1.8854 mg/mL, 0.3767 mg/mL, respectively. The chemical constitution of essential oil from L. Chuanxiong contained terpinen-4-ol (11.81% ), bicycle [2.2.1] heptan-2-ol,1,7,7-trimethyl-,2-acetate(8.28% ), 2-methoxy-4-vinylphenol (14.88% ), valerophenone (7.92% ), benzenemethanol, pentyl-1-hexanol (9.87% ). This was the first time to find that the volatile oil of Ligusticum chuanxiong had better acricidal activity for Teranychus cinnabarinus. The acricidal activity was like that of spirodiclofen (LC50=356.8878 mg/L). And terpinen-4-ol might be one of the effective components.
