摘要: 背景与目的: 观察苜蓿总皂苷的急性毒性和遗传毒性。 材料与方法: 选择昆明种小鼠为受试对象,采用急性经口毒性试验测定苜蓿总皂苷的LD50;采用小鼠骨髓细胞微核试验、小鼠精子畸形试验对其遗传毒性进行评价。 结果: 苜蓿总皂苷的小鼠急性经口LD50为13.01 g/kg;95%可信限为12.46~13.58 g/kg。小鼠骨髓细胞微核和小鼠精子畸形试验结果均为阴性。 结论: 在本实验条件下,苜蓿总皂苷为实际无毒级;未发现遗传毒性。

Abstract: BACKGROUND AND AIM: To observe the acute toxicity and the genotoxicity of alfalfa total saponins(ATS). MATERIALS AND METHODS: Kunming mice were used to test the LD50 of ATS. The mouse bone marrow micronucleus test and the mouse sperm morphology test were used to evaluate genotoxicity of ATS. RESULTS: The LD50 of ATS was 13.01 g/kg, 95% confidence interval was 12.46~13.58 g/kg. The micronucleus rates and sperm abnormality rates were negative. CONCLUSION: The ATS was considered a substance with no toxicity and genotoxicity in this study.

Key words: alfalfa total saponins, acute toxicity, micronucleus test, sperm abnormality
