| 摘要: |
| 用TLC法测知引入中国种植的印楝树皮中含有印楝素;用对印楝素有典型中毒反应的菜青虫、玉米螟所做的生物活性测定结果也表明树皮提取物中含有一定量的印楝素;用HPLC法测定印楝素含量为0.65mg/g干树皮。其结果有助于直接用印楝物质作为杀虫剂及印楝产物综合利用的研究。 |

| Abstract: |
| Azadirachtin was found in the bark of introduced neem tree (Azadirachta indica A. Juss) grown in China by TLC examination. The bioassays made with imported cabbage worm (Pieris rapae) and Asiatic corn borer (Ostrinia furnacalis) having typical poisoning reaction to azadirachtin indicated that the extracts from the crushed bark of neem tree contained a certain amount of azadirachtin. The content of azadirachtin in the bark of neem tree was tested and calculated to be 0.65 mg/g in dried bark by HPLC, those findings could be very helpful to directly use the substances from the neem tree as insecticide and the comprehensive utilization of the products of the neem tree. |
