摘要: 探讨中草药闹羊花用于灭鼠的可行性。方法:在既往试验的基础上,笔者提取了闹羊花叶中根木毒素,并进行了灭鼠试验。结果:闹学花叶煎剂灌服黄胸鼠,20g千叶或80g鲜叶/kg体重,死亡率为100%;10g干叶或40g鲜叶/kg体重,死亡率为60%。闹羊花叶煎汁浸泡大米,16g、6.4g或3.g干叶/g(大米)对黄胸鼠的致死率分别为4.0%、0%、40%;而3.2g干叶/g(大米)对小家鼠的致死率为62.2%。结论:该有毒植物如再经一定的加工,用于灭鼠有一定前途。

Abstract: It was shown that the toxin (Andromedotoxin) of Rhthendron molle had killing efficiency against redents.The LD50 was 35.35 (46.66-26.74) mg/kg for Rattus flauipctus.The toxin content of fresh leaf of Rhthendron,molle was 0.58%, dry leaf 2.32%.The soak fluid had killing efficiency against redents.It is important to raise palatability and technology.
