摘　　要：为深入挖掘我国抑螺植物资源,加大血吸虫病植物防治力度,选择我国重要经济树种、传统土农药——乌桕为对象,对乌桕根、枝、叶和种子等不同器官用4种不同溶剂粗提物的抑螺效果进行分析,发现乌桕不同器官均具有良好的抑螺效果,表明乌桕是一种优良的抑螺植物材料。结果表明,不同器官中以新叶的粗提物抑螺效果最佳,而且前一年的落叶仍表现出良好的抑螺效果,说明乌桕叶具有持续稳定的抑螺特性,其活性物质提取最佳溶剂为石油醚。In order to quest the snail-inhibiting plant resources,and also to enhance schistosomiasis-controlling potential,in this work,we selected the important economic species-the traditional pesticides-Sapium sebiferum as an target object.It was found that there were good effectiveness to control snail in different organs of Sapium sebiferum through the investigation of the snail-inhibiting effect by extraction of effective components in the roots,branches,leaves and seeds of tube Sapium using four solvents,indicating that Sapium sebiferum is a great plant for snail--inhibiting material.By compared,we think that the new leaves were best one for controlling snail,and secondly,the old leaves falled the year before,showing a persisted characteristics of controlling snail.It also showed the petroleum ether was best solvent for extraction of active components among the fours.
