Abstract: BACKGROUND AND AIM: To determine the acute oral toxicity and genetic toxicity of Flammulina velutipes polysaccharide. MATERIALS AND METHODS: Acute oral toxicity test, Ames test,micronucleus test of polychromatic erythrocytes in bone marrow, mice sperm shape abnormality test were used.RESULTS:The acute oral LD50 of Flammulina velutipes polysaccharide was greater than 10 g/kg in mice.The results of genetic toxicity tests were all negative. CONCLUSION: Genetic toxicity of Flammulina velutipes polysaccharide was not found, and it was classified as non_toxic agent.

Key words: Flammulina velutipes polysaccharide, acute oral toxicity, genetic toxicity
