摘要
以林檎叶五组不同提取液对小白鼠进行急性毒性试验和最大安全耐受量实验。结果表明 ,A、C、E、F组的浓度为2 .6g/mL ,没有发现小白鼠死亡 ,其最大安全耐受量倍数为1 32 ,认为安全无毒 ;而D组的死亡率为 80 % ,经进一步实验测定其半致死剂量为 2 .1g/ml,说明经乙醇提取后 。
Five group of extractive materials from malus doumeri leaves were in the study for the acute toxicity test to mice.The results in edicated that dose of Group A、C、E、F was 2.6 g/ml,none mice was found dead,and it was regarded as no toxicity.The death rate in Group D was 80%,which main ingredient was alkaloid dissolved by HCl after extracted with ethanol,50% lethal dose was 2.1 g/ml.
