摘要:

用水蒸气蒸馏法分别提取了益智的根、叶、花及嫩果的植物精油,采用GC/MS分析其化学组成成分,并通过药液浸养法和跗骨接触法测试了益智不同部位精油对白纹伊蚊的毒杀活性。结果表明:益智根、叶、花及嫩果精油的化学组成成分具有显著差异;益智不同部位植物精油均对白纹伊蚊均有毒杀活性,其中益智根精油杀蚊幼活性最好,LC50为40.101 ppm,益智叶精油杀成虫活性最好,LD50为13.04 μg/cm2。本研究结果探究了益智不同部位植物精油的主要化学成分,并为益智进一步开发为灭蚊药物提供了理论依据。

Abstract:

The essential oil from the roots,leaves,flowers and green fruits of Alpinia oxyphylla were extracted by steam distillation and the chemical compositions were analyzed by GC/MS.Four essential oil were tested for the toxic activities against Aedes albopictus by using drug solution culture method and tarsal contact method.The results indicated the chemical composition of essential oils from different parts of A. oxyphylla were significantly different from each other.And comparing the results of the toxic activity of four essential oils against Ae. albopictus,the essential oil from roots showed the highest larvicidal activity with LC50 values of 40.101 ppm,and the essential oil from leaves showed the highest adulticidal activity with LD50 values of 13.04 μg/cm2.The results of this study revealed the chemical compositions of essential oil from different parts of A. oxyphylla,and provided the theoretical basis that the essential oil of A. oxyphylla have the potential to be developed into a novel insecticide against Ae. albopictus.
