摘要: 用索氏提取法以石油醚为溶剂提取制备丁香花蕾中的挥发油组分,用直接接触法和熏蒸法分别测试不同剂量和不同作用时间丁香花蕾油对粉尘螨的杀灭活性,结果显示12.20 μg/cm2丁香花蕾油直接接触粉尘螨后2.5 h死亡率即达100.0%,相同剂量的丁香花蕾油在相对封闭的容器中熏蒸24 h后,螨虫死亡率为100.0%,表明丁香花蕾油对室内粉尘螨具有较好的杀灭活性。

Abstract: Volatile oil from the clove bud was extracted by petroleum ether using Soxhlet Extractor. The acaricidal activity was examined using direct contact and vapour phase toxicity bioassays. In a filter paper contact toxicity bio-assay, at 2.5 h after treatment, clove bud oil at a dose of 12.20 μg/cm2 killed all dust mites. As judged by 24-h LD50 values, potent fumigant action was observed with clove bud oil (12.20 μg/cm2), showing an adequate acaricidal activity against indoor Dermatophagoides farinae.
