Essential oils from aerial parts of the herbs Peganum harmala and Nepeta cataria, and leaves of the tree Phellodendron amurense were analyzed by GC-FID and GC-MS, and their larvicidal activities were assayed on the early fourth instar larvae of Aedes aegypti. The major constituents of the oils were limonene (14.5%) and thymol (11.5%) in P. harmala, thymol (46.5%), 4aα,7α,7aβ-nepetalactone (18.3%) and 4aα,7β,7aα-neptalactone (19.7%) in N. cataria, eugenol (14.5%) andγ-eudesmol (9.5%) in P. amurense.The oil of N. cataria had a strong larvicidal activity (LC₅₀ < 50 µg/mL; LC₉₀ < 86.8 µg/mL) on A. aegypti while the remaining oils showed a moderated killing effect. The larvicidal activity of N. cataria oil was associated to the contents of 1,8-cineol, camphor, 4aα,7α,7aβ-Nepetalactone, 4aα,7β,7aα-Nepetalactone and thymol. Our results indicate that the oil of N. catariadeserves to be used as a source of larvicidal agents against A. aegypti.

用GC-FID和GC-MS分析了从香茅（Peganum harmala）和荆芥（Nepeta cataria）空中部分的香精油以及黄柏（Phellodendron amurense）的叶子，并在埃及伊蚊（Aedes aegypti）的四龄初幼虫上测定了其杀幼虫活性。油中的主要成分是柠檬香茅（P. harmala）中的柠檬烯（14.5％）和百里酚（11.5％），百里香酚（46.5％），4aα，7α，7aβ-荆芥内酯（18.3％）和4aα，7β，7aα-庚内酯（19.7）。 ％）中N. cataria，丁子香酚（14.5％）和γ-桉叶油醇（9.5％）在黄檗的.The油N. cataria产生了强烈的杀虫活性（LC ₅₀  <50微克/毫升; LC ₉₀埃及埃及曲霉的 <86.8 µg / mL），而其余的油则显示出中等程度的杀灭作用。念珠菌油的杀幼虫活性与1,8-木酚，樟脑，4aα，7α，7aβ-荆芥内酯，4aα，7β，7aα-荆芥内酯和百里酚的含量有关。我们的研究结果表明，猪笼草的油值得用作抗埃及伊蚊的杀幼虫剂的来源。
