Abstract:Objective To investigate the natural active compound Usenamine [C18H17NO6, 6-acetyl-2-(1-amino-ethylene)-7, 9-dihydroxy-8, 9b-dimethyl-9bH- diphenylfuran -1, 3-dione] is safe to use. Methods SPF mice were selected for oral toxicity test, in vivo and in vitro chromosomal aberration test, bone marrow micronucleus test, sperm abnormality test and 30-day feeding test. Results Under the research conditions, the maximum tolerated dose (MTD) of the test substance for acute oral toxicity was more than 15000 mg/kg; both in vivo and in vitro chromosomal aberration tests were negative (P > 0.05); bone marrow micronucleus test results were negative (P > 0.05) The result of sperm deformity test was negative (P > 0.05); no obvious signs of poisoning were found in the 30-day feeding test, and all the indicators were normal. Conclusion Usenamine is safe and has no acute or subacute toxic effects, and genetic toxicity. -
