Abstract

Spondias tuberosa Arruda, popularly named as umbu, is native from savanna-like vegetation and widely used for medicinal purposes, however, the toxicological profile is not available yet. This study evaluated the phytochemical profile and acute toxicity and citoxicity of Ethanolic Extract of Spondias tuberosa Arruda Bark (EEStb) in hematological, biochemical and histopathological parameters. Female Wistar rats were divided into: control (C) and animal treated single doses of 300mg/Kg (EEStb300) or 2.000mg/kg body weight (ESStb2.000) of the EEStb. After 24 hours and 14 days from gavage, the behavior, hematological, biochemical and histopathological parameters were assayed. Cytotoxicity effect was evaluated on HEp-2 cell lines. Neither EEStb300nor EEStb2.000produced mortality nor changes in body weight during the 14- days of observation, but EEStb2.000reduced quietly the food and water intake as well as locomotor activity at first day. There were no changes in macroscopic, histopathological, biochemical and hematological parameters. EEStb in concentrations of 6.25- 50μg ml−1on HEp-2 cell did not produce cytotoxic effect. These results suggest that EEStb did not cause acute toxicity and cytotoxic, suggesting a good safety rate for Spondias tuberosa Arruda.
