| 摘 要： | 目的探讨垂序商陆叶杀灭钉螺效果、对钉螺糖原的影响及其对斑马鱼的急性毒性。方法用系统分离法分离垂序商陆叶的各极性部位,采用WHO推荐的＂杀螺剂实验室终筛法＂中的浸泡法进行浸杀灭螺试验,筛选垂序商陆叶的灭螺活性部位;用蒽酮比色法测定灭螺活性部位对钉螺糖原的影响;测定垂序商陆叶极性部位对斑马鱼的急性毒性。结果垂序商陆叶灭螺活性部位集中在乙酸乙酯极性部位,对钉螺48hLC50和LC90值分别为6.0mg/100ml和26.1mg/100ml;垂序商陆叶乙酸乙酯极性部位可使钉螺糖原含量降低20%;在近LC50浓度（48h）的垂序商陆叶乙酸乙酯极性部位作用下,斑马鱼可存活12h。结论垂序商陆叶乙酸乙酯极性部位有较好的灭螺效果,但对斑马鱼有较强的急性毒性。

| Abstract: | Objective To study the molluscicidal activity,the influence on glycogen content of Oncomelania hupensis and the acute toxicity to zebra fish of the extract from Phytolacca americana Linn leaf.Methods The different polar factions of the extract of Phytolacca americana Linn leaf were separated by using the systemic solvent segregation method,and then the molluscicid-al activity of the fractions was detected according to the Laboratory Final Milluscicides Screening Method issued by WHO.The gly-cogen content of... |
