Abstract
Objective To evaluate the safety of tea of Apoeynum venetum leaf.Methods The acute toxicity,Ames test,bone marrow cell micronucleus test,mice sperm abnormality test,and 30-day feeding test were used in this study according to the procedures for toxicological assessment of food.Results The value of MTD for mice was more than 30.0 g/kg.bw,being involved in nontoxic grade.The results of Ames test,bone marrow cell micronucleus test,mice sperm abnormality test were all negative.All indexes in 30-day feeding test were not abnormal.Conclusions The tea of Apoeynum venetum leaf is safe in this study.
