Abstract: BACKGROUND AND AIM: To study the acute toxicity and the mutagenicity of the flavonoids extracted from pteridium aquilinum var. latiusculum. MATERIALS AND METHODS: The oral acute toxicity test, micronucleus test of bone marrow PCE cell and sperm shape abnormality test were carried out. RESULTS: LD50 of the flavonoids extracts from pteridium aquilinum var. latiusculum in rats was more than 20.0 g/kg. The micronucleus rates and sperm abnormality rates in all doses were negative(P>0.05). CONCLUSION: The flavonoids extracted from pteridium aquilinum var. latiusculum was considered a substance with no toxicity and mutagenic activity in this study.

Key words: pteridium aquilinum var. latiusculum, flavonoid, acute toxicity, micronucleus, abnormality
