Abstract | The aim of this study is to contribute to the valorization of the tinctorial plants of Central Africa. A chemical characterization was conducted on three vegetable species presumed tinctorial. Grewia coriacea Mast (Malvaceae), Harungana madagascariensis Lam ex Poir. (Hypericaceae), Annickia chlorantha Oliv. (Annonaceae) were selected because of their traditional use as colouring agents. The classical extractions were done by means of TLC, and quantified by usual methods. The antioxidant activity for the three species has also been assessed.
L’objectif de cette étude est de contribuer à la valorisation des plantes tinctoriales d’Afrique Centrale. Une caractérisation phytochimique est réalisée sur trois espèces végétales présumées tinctoriales. Grewia coriacea Mast (Malvaceae), Harungana madagascariensis Lam ex Poir. (Hypericaceae), Annickia chlorantha Oliv. (Annonaceae) ont été sélectionnées au regard de leur utilisation traditionnelle comme colorant. Les extractions classiques ont été réalisées. Les familles chimiques responsables des propriétés tinctoriales ont été mises en évidence au moyen de la chromatographie couche mince et puis quantifiées par des méthodes usuelles. L’activité antioxydante a été aussi évaluée sur les extraits de ces trois espèces.- |
