Résumé

Background: Natural herbal compounds are a source and alternative for new compounds with anti-inflammatory
properties. Therefore, in-depth studies should be carried out to assess their safety and efficacy in order to avoid or
prevent toxicological risks of these natural plant-based substances. V. doniana is a species of food plant used for
the treatment of inflammatory diseases in Burkina Faso. This study aimed to estimate the anti-inflammatory
properties in vitro and in vivo of the ethyl acetate fraction of the leaves of V. doniana.
Methods: To do this, acute toxicity was first evaluated on the animal model. Biological activities (carrageenan test,
formalin and xylene induced oedemas) were used to assess the anti-inflammatory power.
Results: Regarding the dietary toxicology of the extracts, visual and clinical signs showed that the extracts are not
at the end of the 15-day (acute toxicity) and 45-day (subacute toxicity) tests. In terms of anti-inflammatory activity
in vivo, it was observed that the bioactive fraction (50, 100 and 200 mg/kg.b.w) had effective neurogenic
anti-inflammatory properties. All of these effects observed were all dose-dependent.
Conclusion: The results of this present research have proven that V. donania extracts can be used as antiinflammatories.
