摘　　要：利用蚕豆根尖细胞微核试验方法研究洋葱提取液对环磷酰胺诱导蚕豆根尖微核率的影响。当洋葱提取液的浓度在0.1 g/mL～1.0 g/mL之间,不诱导蚕豆根尖微核率的增加,其微核指数均低于1.5;此外,洋葱提取液能够有效地抑制环磷酰胺诱导的蚕豆根尖微核率的增加,抑制率在19.59%～66.70%之间,与其浓度之间存在一定的相关性,r=0.9745。结果表明洋葱提取液具有一定的抗突变作用。Viciafaba root tips micronucleus test to study on effect of water extract of Allium cepa L. on micronucleus rate of Viciafaba root tips induced by cyclophosphamide, which provided the experimental basis for exploiting the antimutation-function of Allium cepa L. When the concentration of water extract of Allium cepa L. was between 0.1 g/mL and 1.0 g/mL, it did not induce micronucleus rate increases, micronucleus index below 1.5. In addition, it could inhibit the micronucleus rate of Vicia faba root tip cells induced by cyclophosphamide, and the rate of inhibitation was between 19.79 % and 66.70 % , which was in some relationship with the concentration of water extract of Allium cepa L. r=0.974 5. The result of research indicated that the water extract of A Uium cepa L. had some anti-mutation function.
