Isolation of Antimalarial Agents From Indonesian Medicinal Plants: Swietenia mahagoni and Pluchea indica
Natural Product Communications
Malaria is a neglected tropical disease that still demands serious efforts to tackle successfully, including the need for new antimalarial lead compounds to combat drug-resistant Plasmodium. Intensive phytochemical and pharmacological investigation into the Indonesian medicinal plants Swietenia mahagoni and Pluchea indica successfully revealed 5 constituents. Antimalarial bioassays indicated 34,5-tri-O-caffeoylquinic acid (4) to be the most active against Plasmodium falciparum 3D7 and Dd2 strains with IC50 values of 8.2 and 8.8 µM, respectively. No cytotoxicity was observed against Human Embryonic Kidney cells at a concentration of 40 µM.
