Abstract

The anti-malarial activity of 20 quinones isolated from Cassia alataCassia occidentalisGarcinia kola and Ocimum basilicum was investigated in vitrousing the micro dilution test of Desjardin by a visual evaluation on thin blood smears. The six quinones isolated from C. occidentalis, three from C. alata and three from O. basilicum were found to be the most active with an IC50 value of below 1 µg/ml. The others quinones showed moderate activity with IC50 values of between 5 and 20 µg/ml.
