Background: Caryocar brasiliense Cambess (Caryocaraceae) is an arboreal plant native of Brasilian Cerrado and its fruit is an important source of food and income for the human population of this region. In addition to using as food, different parts of this tree have great medicinal potential as antimicrobial, anti-inflammatory, antioxidant and antihelmintic. However, the active metabolites those are likely to confer these pharmacological properties healing may also be toxic dependent upon the dose and route of administration. In this quest, the aim of this study was to assess the acute toxicity of aqueous extracts of fruit peels and leaves of C. brasiliense in mice of both genders. Materials, Methods & Results: The aqueous extracts were obtained by decoction, diluted in water and filtered through membrane. The toxicity of extract of fruit peels (62.5 at 500 mg/kg of body weight (BW) and leaf extract (18.75 mg/kg bw) were evaluated in males and females mice (Mus musculus) Swiss by intraperitoneal route. For 2 control groups were administered injection water. The clinical signs and deaths were recorded up to 14 days after administration. The lethal doses for 10 (LD10) or 50 (LD50) % of population were estimated with Probit regression analysis. The Chi-square test was used to analyze differences of mortality frequencies between males and females. The groups treated with the [...](AU)
