In Lubumbashi and its hinterland, somme food plants which are generating natural colourings used in traditional medicine were found
This is the case of Hibiscus Sabdariffa from which some analyses have been completed in this study namely:
- Moisture and total ash determination in leaves and flowers,
- Chemical matter research,
- Colouring extraction in water, methanol and ethanol
- Biological test of extracted colourant and thermodegradation of colourants.
However, the thermodegradation assessment has been studied by exposition of differents extracts got from study at different temperatures and moments, and the absorbance reading done successively at 262nm for aqueous extracts and at 268nm for both methanolic and ethanol extracts
Author Keywords: Hibiscus Sabdariffa, Extract, Anti-Sickling, Thermodegradation.

Abstract: (french)
A Lubumbashi et dans son hinterland l'on rencontre des plantes alimentaires sources des colorants naturels et utilisées en médecine traditionnelle. C'est le cas de l'Hibiscus Sabdariffa qui a fait l'objet de cette étude.
La détermination dans les feuilles et les fleurs de l'humidité et de la cendre totale, ainsi que la recherche des substances chimiques, l'extraction des colorants dans l'eau, dans le méthanol et dans l'éthanol, l'évaluation des propriétés antidrépanocytaires de ces colorants et de leur thermo dégradation ont été effectuées au cours de cette étude.
La thermo dégradation a été étudiée en exposant les différents extraits obtenus à l'étuve à différentes températures et à différents temps et la lecture de l'absorbance faite à 262 nm pour les extraits aqueux et à 268 nm pour les extraits méthanoliques et éthanoliques.
Author Keywords: Hibiscus Sabdariffa, Extraits, Activité antifalcémiante, Thermo dégradation.
