Objective:To measure the half lethal dose(LD50)of petroleum ether extract and ethyl acetate extract of Euphorbia fischeriana Steud in mice.Method:Totally 150 kunming mice in half genders were randomly divided into corresponding groups,each had 10 mice.Intraperitoneal injection the mice with extractive of Euphorbia fischeriana Steud and observe the toxic symptom,and the LD50 and 95% confidence interval of the drug was measured with acute mortality rate as index.Result:The half lethal dose(LD50)of petroleum ether extract and ethyl acetate extract of Euphorbia fischeriana Steud in mice were 31.03 mg/kg,1538.58 mg/kg.Conclusion:The petroleum ether extract and ethyl acetate extract of Euphorbia fischeriana Steud have some toxicity.The experimental result provided toxicity data for further research and development.
