Abstract: Purpose : To study the antimutagenicity of Oridonin Methods : Ames test and micronucleus assay of polychromatic erythrocytes in mice bone marrow were used. Results : Oridonin could evidently inhibit the reverse mutation on S almonella typhimuriun st rains TA98 and TA100 without S9mix. The rates of maximum inhibition were 89. 1 % and 80. 2 % respectively. In addition , Oridonin could significantly reduce micronucleus requencies induced by cyclophosphamide ( P < 0. 01) . Conclusion : Oridonin has significant antimutagenic effect .

Key words: Oridonin, antimutagenicity, Ames test, micronucleus test
