摘要:
Vernonia colorata is used throughout Africa to treat various ailments. Its antiplasmodial activity has been widely reported. Using bioassay-guided fractionation, we isolated two antiplasmodial compounds - vernolide (IC(5)0=1.87 mu g/ml) and vernodalin (IC50=0.52 mu g/ml) with selective indices of 1.02 and 2.79 for vernolide and vernodalin respectively. These compounds are non-specific towards parasites. (C) 2008 SAAB. Published by Elsevier B.V. All rights reserved.
