Objective To evaluate acute toxicity and genotoxicity of sapindus saponin and to provide toxicological basis for sapindus saponin's daily applications. Methods Acute oral toxicity test,mammalian erythocyte micronucleus test,bacterial reverse mutation test and in vitro mammalian chromosome aberration test were used to investigate the effect of the sapindus saponin on gene mutation and chromosome aberration in both prokaryotic and eukaryotic cells. Results The acute toxicity test showed that the LD50 of sapin...
