乌桕·枫杨和柳杉乙醇提取液的灭螺活性比较

摘要

[目的]比较乌桕、枫杨和柳杉己醇提取液的灭螺活性.[方法]采用室内浸杀钉螺试验,测定了鸟桕、枫杨和柳杉乙醇提取液的灭螺活性.[结果]乌桕、枫杨和柳杉乙醇浸提液均具有一定的灭螺效果,其中乌桕和柳杉灭螺效果较好且相差不大,而枫杨相对较差;采用乙醇能较好地提取植物的有效灭螺成分,其灭螺效果比植物的水浸液要好.[结论]为生态柳螺植物材料的筛选提供了理论依据.%[ Objective ] The aim was to compare molluscicide activity of ethanol extracts of Sapium sebiferum, Pterocarya stenoptera and Cryptomeria fortunei. [ Method ] The molluscicide activity of ethanol extracts of Sapium sebiferum, Pterocarya stenoptera and Cryptomeria fortunei were determined with indoor killing experiment. [ Result] Sapium sebiferum, Pterocarya stenoptera and Cryptomeriafortunei exhibited activity against Oncanelania hupensis. Among them, the molluscicide activity of Sapium sebiferum and Cryptomeriafortunei was similar, but the activity of Pterocarya stenoptera was relatively poor. The effective components of plants were extracted more completely, so the molluscicide activity of ethanol-extracts was stronger than water-extracts. [ Conclusion] The study will provide theoretical basis for screening molluscicide plants.
