RESUMO
Bartogenic acid (BA), an active pentacyclic triterpenoid, has been reported for anti-diabetic, anti-inflammatory, anti-arthritic, anti-cancer, and anti-tumor activity. However, toxicity profiling of BA has not been reported till date. Hence, this study is designed to evaluate the single dose (12.5, 25, 50 and 100 mg/kg) and repeated dose (1.5, 6, and 24 mg/kg) intravenous toxicity of BA in BALB/c mice. Control group received vehicle. In single dose toxicity study, two mortalities were observed at 100 mg/kg of BA whereas lower doses were well tolerated. In repeated dose toxicity study, no mortality was observed. 1.5 mg/kg of BA was well tolerated in mice of both sexes. At 6 mg/kg of BA, female mice showed significant reduction in the body weight as compared to the control group however no significant change was observed in male mice. 24 mg/kg of BA showed significant reduction in the body weight in mice of both sexes. Further, these mice showed significant change in the relative organ weight. However, no toxicologically relevant changes were observed in hematology, biochemistry, and histopathology. Based on the findings, No-Observed-Adverse-Effect-Level (NOAEL) for BA were found to be<24 mg/kg for male mice and<6 mg/kg for female mice.
