The root powder of Stellera chamaejasme was extracted with petroleum ether. The crude extract obtained was chromatographed repeatedly with silica gel columns. One pure natural product was obtained, which was identified as 5-isopropyl-2-methylphenol (carvacrol), separated for the first time from the root of S. chamaejasme. The results of a laboratory bioassay showed that it had good insecticidal activity against Aphis craccivora and Leucania separata. Its median lethal concentrations (LC(50)) (24 h after treatment) were 16.8 and 12.7 mg L(-1), respectively. This is the first report of the insecticidal activity of carvacrol against A. craccivora and L. separata.
瑞香狼毒根粉用石油醚提取。得到的粗提取物用硅胶柱反复层析。得到一个纯的天然产物，鉴定为 5-异丙基-2-甲基苯酚（香芹酚），这是首次从瑞香狼毒根中分离得到。实验室生物测定结果表明，它对桃蚜和榆蓝叶甲具有良好的杀虫活性。处理后 24 小时的 LC50 分别为 16.8 和 12.7 mg/L(-1)。这是香芹酚对桃蚜和榆蓝叶甲杀虫活性的首次报道。
