摘　　要：目的 进行山豆根水提组分对咽喉实热证小鼠的急性毒性研究,以阐释清热解毒类有毒中药“毒性-证候”相关性。方法 制备山豆根水提组分样品,建立小鼠咽喉实热证模型,采用经典的小鼠急性毒性实验方法给模型小鼠灌胃山豆根水提组分进行急性毒性实验,连续观察14天,观察其急性毒性症状、体征,记录累积死亡率和小鼠体重变化,计算LD50。结果 山豆根水提组分给咽喉实热证模型小鼠灌胃后小鼠出现烦躁、呼吸抑制等急毒症状、体征,LD50及其95%可信限为20.63（17.94-23.92）g·kg^-1。结论 山豆根水提组分对咽喉实热证模型小鼠的急性毒性明显小于正常动物,毒性症状出现时间延后,毒性症状减轻,LD50值增大。Objective The acute toxicity of water extract of Sophorae tonkinensis Radix et Rhizome on mice was researched to determine the correlation of ＂toxicity-syndrome＂. Methods The sample water extract of Sophorae tonkinensis Radix et Rhizome was administrated to KM mice of the throat excess-heat syndrome models. The LD 50 of Sophorae tonkinensis Radix et Rhizome was tested by the classical methods of acute toxicity. The acute toxic symptoms were observed, the accumulated death number and the weight-changes of live mice were recorded. Results The LD50 and its 95% confidence limits of water extract of Sophorae tonkinensis Radix et Rhizome was 20.63 （17.94-23.92）g·kg^-1 in mice. Restlessness, breathlessness and convulsion were the main acute toxic symptoms. Conclusion The acute toxicity of water extract of Sophorae tonkinensis Radix et Rhizome on throat excess-heat syn drome mouse model in mice was significantly less than normal animals. The onset time of toxic symptoms was delayed and relieved, the LD50 value was increased.
