[目的]考察生附子醇提物的经口急性毒性。[方法]以70%为溶媒,用索氏提取法制备附子浸提物,经预试验获得正式试验最大给药剂量,设计7个剂量组,组间距1.7倍,给昆明系小鼠灌胃给药一次,剂量为0.04ml/(g·BW).观察7d,用改良寇酗去公式计算半数致死量(LD50)及其95%可信限。[结果]附子醇提物给小鼠经口LD50为230.12mg(kg·BW),LD50的95%可信限为80.39~658.57mg/(kg·BW)。[结论]生附子醇提物可快速引起小鼠出现急性毒性。
[Objective] This study aimed to investigate the acute oral toxicity of crude monkshood (Radix aconiti lateralis preparata). [Method] Monkshood alcohol extract was prepared using soxhlet extractor. The maximum drug dose, which was the minimum dose causing 100% lethally rate in the preliminary test, was diluted into seven con- centrations in formal test. Then every mouse was orally administrated with 0.04 ml/g of the monkshood solution at single time for 7 d. Median lethal dose (LD50) and 95% confidence limit were calculated by the improved Karber method formulas. [Result] LD50 of monkshood ethanol extract was 230.12 mg/kg and 95% confidence limit of LD50 was 80.39-658.57 mg/kg. [Conclusion] Crude monkshood alcohol extract can quickly induce acute toxicity in mice.
