Astilbin is an active flavonoid compound isolated from Rhizoma Smilacis Glabrae. It has been widely used as an anti-hepatic, anti-arthritic, and anti-renal injury agent. However, its safety has not yet been established. The objective of this study was to evaluate 4-week repeated oral toxicity and genotoxicity of astilbin. We examined oral toxicity in Sprague-Dawley rats after daily oral administration of astilbin at 50, 150, and 500 mg/kg for 4 weeks. Negative control animals received the same volume of the solvent. Astilbin administration did not lead to death, body weight gain, food consumption, or adverse events. There were no significant differences in toxicity between the astilbin and control group; we observed no toxic effects on hematological or urinalysis parameters, biochemical values, organ weight, or histopathological findings. We assessed the genotoxicity of astilbin with the Ames test (TA97a, TA98, TA100, TA102, and TA1535), chromosomal aberration assay (using Chinese hamster ovary cells), and mammalian micronucleus test (in mice). We found no genotoxicity in any tested strains. The no-observed-adverse effect level (NOAEL) for astilbin in the 4-week repeated oral toxicity study in rats was greater than 500 mg/kg body weight/day, regardless of gender. Results also suggested that astilbin does not have genotoxicity potential. (C) 2017 Elsevier Ltd. All rights reserved.
