For centuries. malaria was treated with the bark of Cinchona calisaya and Cinchona succirubra plants named quinas in Brazil, from which the quinine molecule was isolated. Other plant species known also as quinas are used to treat fever and malaria, like Deianira erubescens (roots and leaves). Strychnos pseudoquina (bark), and Remijia ferruginea (bark). Based on this popular knowledge, we evaluated the in vivo antimalarial activity of the ethanol crude extracts of these plant species in mice infected with Plasmodium berghei. Only Remijia ferruginea showed antimalarial activity, reducing parasitaemia and mortality at the highest dose tested. Its phytochemical analysis showed the presence of alkaloids but not quinine. The other two plant species were inactive. (C) 2003 Elsevier Science Ltd. All fights reserved.
