ACTIVITE ANTIINFLAMMATOIRE DE LA GRAINE DE CARAPA PROCERA (MELIACEAE)
Abstract
Résumé : le Carapa procera (Meliaceae) est une plante très utilisée dans la médecine traditionnelle sénégalaise. Cette étude concerne l’évaluation de l’effet anti-inflammatoire de la graine de Carapa procera. L’objectif de ce travail est non seulement de montrer l’effet de l’extrait de la graine de Carapa procera sur l’inflammation, mais également d’identifier les principes actifs. La méthodologie utilisée, pour évaluer l’effet anti-inflammatoire des divers extraits, est celle qui étudie in vivo l’évolution de l’oedème podal de rat provoquée après l’injection intraplantaire de carragéenine, un agent phlogogène qui induit des foyers inflammatoires. Des rats Wistar, répartis en lots de 5, mis à jeun pendant 16 heures, ont été utilisés pour réaliser cette étude. L’étude in vivo des extraits apolaires et polaires, a permis de mettre en évidence l’effet anti-inflammatoire de l’extrait de graine de Carapa procera et de le localiser dans les fractions apolaires. De plus, nous
avons pu montrer que les insaponifiables étaient responsables de l’effet anti-inflammatoire de l’extrait étudié. Un bon effet anti-inflammatoire des insaponifiables, comparable à celui de l’aspirine, a été observé à 30 mg/kg.
Mots clé: Carapa procera, Meliaceae, insaponifiables, effet anti-inflammatoire.
Abstract: Carapa procera (Meliaceae) is currently used plant in Senegalese traditional medicine. This study relates to the evaluation of the anti-inflammatory effect of the seed of Carapa procera. The aim of this work was not only to show the effect of the seed of Carapa procera extract on inflammation, but also to identify the active ingredients. The experimental approach used to assess the anti-inflammatory effect of the various extracts was the evaluation of the evolution of the rat paw oedema caused by intraplantar injection of carrageenan, a Mbaye Diaw DIOUM et al 18
phlogogenic agent known to induce inflammatory foci.Wistar rats, divided into groups of five and fasted for 16 hours, were used for this study. The in vivo evaluation of the non-polar and polar extracts, allowed us to localize the anti-inflammatory effect in the non-polar fractions. Moreover, we have shown that the unsaponifiables were responsible for the anti-inflammatory effect. A significant effect of the unsaponifiable sat 30 mg/kg was comparable with the effect of aspirin.
