目的 研究麻风树籽提取物杀灭钉螺的效果。方法 采用室内浸杀法,对麻风树籽的乙醇提取物和水提取物的杀螺效果进行观察。结果 麻风树籽乙醇提取物浸杀钉螺24、48 h和72 h的LC_(50)分别为53.7、25.3 mg/L和11.6 mg/L;水提取物浸杀钉螺48 h和72 h的LC_(50)分别为45.6mg/L和26.1 mg/L。结论 麻风树籽乙醇提取物和水提取物对钉螺均具有杀灭作用。麻风树籽是研究植物杀螺剂较有价值的候选植物。
Objective To study the effect of Jatropha curcas seed extract in killing snails. Methods By indoor immersion method, the effects of Jatropha seed ethanol extract and water extract were observed. Results The results showed that the LC 50 values of Jatropha curcas seedling soaked in snails for 24, 48 and 72 h were 53.7, 25.3 mg / L and 11.6 mg / 50) were 45.6 mg / L and 26.1 mg / L, respectively. Conclusion Both Jatropha curcas seed ethanol extract and water extract can kill snails. Jatropha seed is a more valuable candidate plant for studying plant-killing agents.
