Investigating South African plants as a source of new antimalarial drugs.
Based on the historical success of natural products as antimalarial drugs and the urgent need for new antimalarials, a number of South African medicinal plants have been evaluated for their antimalarial properties. This paper reviews the major studies conducted and their findings. Overall three ethnobotanical screening programmes have been conducted on South African plants while there have been a few studies adopting a more direct approach, where plants within a particular genus were screened for antiplasmodial activity. The paper also summarizes the bioactive molecules identified from selected plants having antiplasmodial activity. Overall the results of all studies conducted to date confirm the potential of South African medicinal plants in antimalarial drug discovery and identified a number of promising taxa and compounds for further investigation as plant-based antimalarial agents.
