香芹酚对粘虫的毒杀活性研究

Study on Poisonous Activity of Carvacrol against Leucania separate

[目的]研究瑞香狼毒根中2甲-基-5异-丙基苯酚对粘虫的毒杀活性。[方法]提取纯化瑞香狼毒根粉中的化合物A并分析,然后进行对粘虫毒杀活性的测定。[结果]化合物A对粘虫有较好的毒杀活性,处理24 h后的致死浓度(LC50)为12.7 mg/L。[结论]首次从瑞香狼毒根中分离得到了2甲-基-5异-丙基苯酚,这将为新型植物源农药的研究和开发奠定较好的基础。

[Objective]The propose was to study on the poisonous activity of 2-methyl-5-isopropyl phenol in the root of Stellera chamaejasme against Leucania separate.[Method]The compounds A was extracted from the purified root powder of S.chamaejasme and its poisonous activity against L.separate was determined.[Result] The compounds A had better poisonous activity against L.separate and then its lethal concentration（LC50） after treatment for 24 h was 12.7 mg /L.[Conclusion]It was the first time to separate 2-methyl-5-isopropyl phenol from the root of S.chamaejasme,which will lay a good foundation for the research and development of new plant-based insecticides.
