Background: Aloe macrocarpa Todaro is one of the Aloe species in Ethiopia where its leaf exudate is traditionally used for the treatment of various ailments, including malaria.
Methods: Two pure compounds namely aloin and aloinoside were isolated from the leaf exudate. Further oxidative hydrolysis yielded another compound (aloe-emodin). Four-day suppressive test was employed to evaluate the antimalarial potential of the leaf exudates and isolated compounds as well as aloe-emodin against mice infected with Plasmodium berghei.
Results: The leaf exudate of A. macrocarpa showed significant chemosuppression of P. berghei at all dose levels tested compared to the negative control group. At a dose of 400 mg/kg, the leaf exudate of A. macrocarpa, the isolated aloin as well as the semi.. View More»
