Abstract: To evaluate the edible safety of green tea buccal tablets(GTBT), tests included acute toxicity test, Aames test, Micronucleus test, Sperm shape abnormality test and thirty days feeding test were performed. Results shows that: The oral maximum tolerated dose(MTD) was higher than 20.0βg／kg·bw both in male or female mice and rats. Ames test, Micronucleus test and Sperm shape abnormality test were positive. No significant toxicity was detected in thirty days feeding test. Conclusion: Green tea buccal tablets has no acute toxicity, no genotoxicity, high in edible safety.
