摘　　要：为研究贯众、苦参、川楝子、土木香等4种中药对鲫鱼的急性毒性作用,我们采用生物毒性方法,观察和记录了投药96 h内鲫鱼的死亡情况和毒性反应。结果显示:4种中药的毒性大小依次为贯众>川楝子>苦参>土木香,24 h的半致死质量浓度(LC50)分别为2.254、10.239、36.363、47.539 g/L,安全质量浓度(SC)分别为0.294、1.539、8.575、10.076 g/L。结论:在鲫鱼养殖中使用上述中药时应在其安全质量浓度范围内进行。Biological toxicity method was adopted to investigate the acute toxicity effect of four Chinese herbs（Cyrtomium fortune, Sophora, Toosendan and Elecampane） on carassius auratus by observing and recording the death and toxic reaction of carassius auratus within 96 h. The resuhs indicated that toxicities of the four Chinese herbs decreased in the following sequence： Cyrtomium fortune〉Toosendan〉Sophora〉Elecampane. The median lethal concentrations （LC50） of these four Chinese herbs were 2.254, 10.239, 36.363 g/L and 47.539g/L, respectively, and their corresponding safe concentration （SC） were 0.294, 1.539, 8.575 g/L and 10.076g/L, respectively. Therefore, once these four Chinese herbs were used in culture of carassius auratus, their dosages must be controlled within each safety concentration range.
