title: Thirteen-week repeated dose toxicity of Siraitia grosvenori extract in Wistar Hannover (GALAS) rats.
abstract: Siraitia grosvenori extract has been used as a food additive. As a part of the safety assessment of the extracts, a 13-week repeated dose toxicity study was performed in Wistar Hannover (GALAS) rats. Male and female rats were divided into five groups consisting of eight animals each and given diet containing 0%, 0.04%, 0.2%, 1%, and 5% of S. grosvenori extract for 13 weeks. During the experiment, no deaths were observed in any groups, and there were no remarkable changes in general appearance, body weight, food and water consumption, hematological and serum biochemical parameters, organ weight and histopathological findings between the control and treated groups. On the basis of these data, the no-observed-adverse effect level (NOAEL) of S. grosvenori extract in Wistar Hannover rats was considered to be 5% (2520 mg/kg/day in males and 3200 mg/kg/day in females) or more.
