Antidrepanocytary activity of Ipomoea batatas, an edible and therapeutic plant used in traditional medicine of Katanga for burns and sickle cell disease was evaluated using the Emmel test. Crude extracts extracted by water, methanol and ethanol, have shown activity antidrepanocytory activity in vitro.
The chemical screening showed that the leaves of Ipomoea batatas mainly contain alkaloids, flavonoids, tannins, quinones, leucoanthocyanes, saponins and steroids.
The evaluation of the effect of heat, studied by UV-Visible spectrophotometry at 262nm for the aqueous extracts and at 268nm for the methanolic and ethanolic extracts by exposing extracts obtained in the oven at various times and temperatures, have shown that crude substances extracted from Ipomoea batatas are heat sensitive.

Abstract: (french)
L'activité antidrépanocytaire de Ipomoea batatas, une plante comestible à vertu thérapeutique utilisée dans l'alimentation, et en médecine traditionnelle Katangaise pour les brulures et l'anémie SS, a été évaluée en utilisant le test d'Emmel. Les substances brutes extraites par l'eau, le méthanol et l'éthanol, ont montré in vitro une activité antifalcémiante.
Le criblage chimique a montré que les feuilles de Ipomoea batatas contiennent principalement les alcaloïdes, les flavonoïdes, les tanins, les quinones, les leucoanthocyanes, les saponines et les stéroïdes.
L'évaluation de l'effet de la chaleur, étudiée par spectrophotométrie UV-Visible à 262nm pour les extraits aqueux et à 268 nm pour les extraits méthanoliques et éthanoliques en exposant les différents extraits obtenus à l'étuve à différents temps et températures, a montré que substances extraits de Ipomoea batatas sont thermosensibles.
Author Keywords: Ipomoea batatas, activité antifalcémiante, thermodégradation, Test d'Emmel.
