Abstract: BACKGROUND & AIM:To check the embryo toxicity, acute toxicity, and accumulation toxicity of water extract from the pulp of cornus. MATERIALAND METHODS:Acute toxicity test,accumulation toxicity test and teratogenicity test were used in this study. RESULTS: The test result showed that:LD50>10 g/kg,accumulation coeffcient K>5. There was no significant difference between the water extract from the pulp of cornus and negative control,but there was significant difference compared to positive control. CONCLUSION: The water extract has no acute toxicity,accumulation toxicity on the mice,and no embryhotoxicity on the embryo of mice.

Key words: pulp of cornus, the matter extracted by water, acute toxicity, accumulative toxicity, embryotoxicity
