    Structrual Identification of Azadirachtin from the Seeds of Introduced Azadirachta indica A. Juss Planted in China

      摘要
    • 摘要: 采用硅胶柱层析法从国产印楝（Azdirachta indica A.Juss)种子中分 离得到化合物FI5,经波变分析确定其结构为印楝素，并验证了印楝素的拒食活性。

       

      Abstract: The substance FI 5 was isolated from the seeds of introduced neem trees ( Azadirachta indica A. Juss) planted in China by open column chromatography on silica gel. On the basis of spectroscopic analysis its structure was identified as azadirachtin. The result of no choice antifeedant experiment against the larvae of Pieris rapae showed that it had the most potential antifeedant activity.
