摘　　要：通过对苦参不同部位杀鼠活性的测定,结果表明,在20％浓度时,苦参根、茎叶对小白鼠个体的毒杀率分别为100％和50％;在15％浓度时分别为100％和20％。饵料中苦参根、茎叶的含量为20％时,试鼠的摄食系数分别为0.59和0.72。说明苦参对试鼠有较好的毒杀活性以及较好的适口性。以家鸡进行安全性试验,无二次中毒现象。The killing rat activity of Sophora flavescens of different parts were measured. The results indicated that the killing rat rate of Sophora flavescens root. Stem and leaf at 20% were 100% and 50% respectively;at 15%,were 100% and 20% respectively. Intake coefficient to food that contained Sophora flavescens root. Stem and leaf at 20% were 0. 59 and 0. 72 respectively. The safety experiment with chicken had not secondary poisoning.
