Abstract: Purpose: To study the acute toxicity and the mutagenicity of Chuanbeipiba polysaccharides. Methods: The oral acute toxicity tests in rats and mice, Ames test, micronucleus test of polychromatic erythrocytes in bone marrow and sperm shape abnormality test were carried out. Results: LD50 in rats and mice were more than 10 g/kg; The micronucleus rates and sperm abnormality rates in all doses were not significantly different from the control group(P>0.05), respectively. But those rates in positive group were higher than in the negative control group(P<0.01).No increase in the number of revertant colonies was found in the Ames test with and without S 9 mix Conclusion: Acute toxicity and the mutagenicity of Chuanbeipiba polysaccharides were not observed in this study.

Key words: chuanbeipiba polysaccharides, acute toxicity, mutagenicity
