Anti-Inflammatory and Antibothropic Properties of Jatropha Elliptica, a Plant from Brazilian Cerrado Biome

The aim of this study was to evaluate the antibothropic and anti-inflammatory properties of J. elliptica.
Phytochemical screening and thin-layer chromatography (TLC) assays were performed on J. elliptica hydroalcoholic extract (TE) in order to observe its main constituents. The antibothropic activity of TE was evaluated by the in vitro neuromuscular blockade caused by Bothrops jararacussu venom (Bjssu), in a mouse phrenic nervediaphragm model (PND). A quantitative histological study was carried out to observe a possible protection of TE against the venom myotoxicity. The anti-inflammatory activity was also evaluated in two models, Bjssu-induced paw edema, and carrageenan-induced neutrophils migration in the peritoneal cavity.
TLC analysis revealed several compounds in TE, such as saponins, alkaloids, and phenolic constituents. TE was able to neutralize the blockade and the myotoxicity induced by venom, when it was pre-incubated for 30 min with venom. In addition, it showed antiinflammatory activity, inducing less neutrophils migration and reducing paw edema.
J. elliptica showed both antibothropic and anti-inflammatory properties.
